Term Definition
Antenna
A device that transmits and receives wireless signals, defined by its type, size, and configuration, which affect signal range, direction, and quality.
  • External antennas on adjustable mounts can improve range and signal directionality
  • Internal antennas help reduce overall device size and simplify enclosure design while still supporting reliable communication in compact systems
Accuracy (% of Span)
The maximum total deviation between the measured value and the true input, expressed as a percentage of the full-scale measurement range. It typically accounts for non-linearity, hysteresis, and repeatability.
  • In many specifications, accuracy may be simplified and presented only as non-linearity, but true accuracy often includes other error sources
  • Accuracy is a key performance indicator in applications that require high precision, such as legal-for-trade weighing, calibration systems, or quality-controlled
  • Accuracy differs from resolution (the smallest measurable increment) and precision (consistency of repeated measurements), and should not be used interchangeably with those terms.
Analog Input Range
The maximum voltage or current range that an analog input channel can safely accept, such as ±30 mV or ±10 V.
  • The input range defines the limits of usable signal that can be digitized without clipping or distortion. Signals outside this range may be clamped, ignored, or cause measurement errors—even if overload protection prevents physical damage.
  • Always allow 10-20% headroom for dynamic signals, electrical noise, or sensor overshoot. For example, a ±10 V input range should not be driven with a signal that peaks near ±10 V if noise or transients are expected.
Analog Input Type
The type and range of analog signals that a device is designed to accept from external sensors, such as 0–30 mV, 0–10 V, or 4–20 mA
  • To ensure proper signal acquisition and scaling, the sensor output type must match the device’s input specification.
  • For example, unamplified sensors like load cells typically output millivolt-level signals (e.g., 0–30 mV) and require devices with mV-range inputs. Connecting them to a 4–20 mA input will result in no usable signal.
  • Always confirm whether the device expects a voltage or current input, and check excitation requirements, especially for bridge-based sensors.
Analog Output Type
The analog signal format and voltage/current range used to retransmit the measured input. Common examples include 0–10 V, ±10 V, and 4–20 mA, representing the full-scale measurement span of the device.
  • Current outputs (especially 4–20 mA) offer superior noise immunity and are less affected by cable length or resistance, making them the preferred choice for industrial environments and long cable runs.
  • Ensure that receiving devices (e.g., PLCs, analog inputs) are compatible with the output signal type and range for accurate interpretation.
Analog Outputs
A retransmission of the measured signal as a continuous voltage (e.g., 0–10 V) or current (e.g., 4–20 mA) to external devices.
  • Typically used in process control systems, PLCs, or data loggers.
  • Less common on basic indicators; more likely on advanced or industrial models.
  • Ensure signal type and scaling are compatible with connected devices.
Brightness (mcd)
The luminance of the display, measured in millicandelas (mcd), indicating how visible the screen is under different lighting conditions.
  • Candela measures light intensity in a specific direction, making it appropriate for backlit displays.
  • Not to be confused with lumens, which measure total light output in all directions (e.g., flood lights).
Certification
Regulatory approvals required for legal operation (i.e. NTEP, CE, IECEx, FCC, etc.)
  • Required for compliance in hazardous areas or when financial transactions or regulation affect or are part of the use case of the product
  • Certain approvals can increase cost and lead time of a product (i.e. ATEX)
Channel Count
The number of independent input channels a device can measure and process simultaneously.
  • Some units can power multiple sensors but share a single measurement channel
  • True multi-channel devices allow simultaneous, isolated readings and are ideal for applications requiring multiple sensor inputs in a compact setup
CMRR
CMRR is a measure of an amplifier or signal conditioner’s ability to reject common-mode signals—voltages that appear identically on both input lines—while amplifying only the differential signal. It is usually expressed in decibels (dB).
  • Higher CMRR improves noise immunity, especially in low-level signal applications.
  • Common-mode noise often comes from EMI, ground loops, or long cables.

  • Always verify the rating based on installation location and exposure conditions.
Frequency Band (MHz/GHz)
The portion of the RF spectrum used for communication (e.g., 902–928 MHz, 2.4 GHz).
  • License-free frequency bands vary by region; always ensure compliance with local regulations (e.g., FCC, IC, CE).
Gain (V/V)
The ratio of output voltage to input voltage applied by the amplifier—expressed in volts per volt (V/V). This determines how much the input signal is amplified before being passed to the output or A/D converter.
  • Gain may be digitally programmable (via software or communication interface) or manually adjusted using onboard potentiometers, depending on the device.
  • Selecting the correct gain allows you to scale low-level sensor signals (e.g., mV from a load cell) to match the input range of an ADC or control system, maximizing resolution and accuracy.
  • Improper gain settings may lead to signal clipping (if too high) or reduced sensitivity and poor SNR (if too low).
Ingress Protection
IEC 60529 rating that indicates dust and water ingress resistance. The first digit indicates solid particle ingress protection while the second digit indicates water ingress protection.
  • IP67 is typically the minimum recommended rating for washdown applications
  • IP ratings are independent of material and corrosion resistance
Input Power (VDC/VAC)
The voltage range required to power the device. Some models include internal rectifiers to support direct AC connection, while others require a dedicated DC power supply.
  • Most devices are designed to accommodate 100-240VAC or between 8-24VDC without compromising performance, allowing for ease of integration despite different global electronics standards.
  • ANYLOAD units are fully tested within their specified power ranges to ensure consistent operation, stability, and measurement accuracy across the entire range.
Installation Mounting
The physical method by which the device is installed, such as panel-mounted, DIN-rail mounted, or wall-mounted, depending on the application and enclosure design.
  • Proper mounting ensures mechanical stability, vibration resistance, and safe operation in industrial environments.
  • Always verify torque specifications, screw length, and material compatibility when using brackets or adapters to avoid damaging the housing or compromising IP-rated seals.
  • Certain devices may require a specific orientation for ventilation, display visibility, or ingress protection; refer to product documentation.
Isolation
Electrical separation between different parts of a circuit to prevent unwanted current flow and protect against voltage spikes or ground loops.
  • Enhances safety, prevents interference, and protects sensitive components.
  • Common isolation methods include optical, transformer, and capacitive coupling.

  • Accessories such as swivel brackets or tilt plates can be optioned to increase installation versatility.
Network Topology
The communication structure used between devices, such as point-to-point, star, or mesh networks.
  • A key consideration when designing systems with multiple wireless nodes. Mesh networks offer better scalability and redundancy but may increase complexity and latency compared to simpler topologies.
Noise
Unwanted electrical disturbances that interfere with the accuracy or stability of an analog or digital signal. Noise can originate from internal circuit behavior or external sources such as electromagnetic fields or ground loops.
  • Effects of additional can be mitigated by converting the signal to a larger, more resilient analogue signal or to a digital signal.
  • High-impedance sensor outputs and long analog cable runs are particularly susceptible to noise.
Operating Temperature (°C/°F)
The allowable ambient temperature range within which the device is guaranteed to operate reliably and maintain specified performance.
  • All ANYLOAD products are tested within their stated operating temperature range; use outside this range may result in measurement drift, loss of accuracy, or permanent damage to internal components.

Power Consumption (W)
The amount of electrical power consumed by the device, typically specified as either a typical operating load or a maximum draw under full functionality.
  • This value is important when selecting an appropriate power supply and ensuring that the device does not exceed available system capacity.
  • In panel-mounted or enclosed installations, power consumption contributes to internal heat generation and may influence thermal management design (e.g., ventilation or heat sinking).
Range (LoS)
Maximum communication distance under line-of-sight (LoS) conditions.
  • Obstacles, such as walls, machinery, or terrain, can significantly reduce range in real-world deployments.
Response Time (ms)
