Description
The 8803809706 (Model Temp-WM) is a microprocessor-based temperature transmitter designed for high-accuracy ambient monitoring within commercial buildings and industrial spaces. The device integrates a highly stable thermal sensor and converts real-time ambient measurements into a linear 4 to 20 mA analogue output signal. Built on a 2-wire loop-powered architecture, it reduces wiring complexity while allowing for reliable, long-distance signal transmission directly to PLCs or Building Management Systems (BMS). Operators can seamlessly recalibrate the unit or alter the output scaling configuration using the proprietary TxConfig-USB interface module alongside the SigNow setup utility.
Features
- Microprocessor-Driven Loop: Delivers a highly precise, linear 2-wire 4 to 20 mA or 20 to 4 mA analogue current loop output.
- Low-Profile Wall Enclosure: Features a compact, aesthetically neutral PA-GF plastic body optimised for surface mounting in public or workspaces.
- Fully Configurable Scaling: Comes with a default calibrated temperature range of −20°C to +70°C, which can be modified custom via software.
- Built-in Power Safety: Includes internal structural protection against reversed voltage supply line polarity to eliminate field deployment damage.
- Clean Galvanic Isolation: Engineered with native electrical isolation between the inputs, output, and power supply loop to preserve signal purity in environments with heavy electrical noise
