Product information "Weighing transmitter WTM"

The WTM transmitter can be used to set up weighing applications with 8 independently functioning channels. (Using a 24-bit A/D converter) it converts the analogue output signals of the connected load cells into a stable digital weight value.

The analogue and digital outputs with stable weight data enable a wide range of applications, and the different interfaces ensure easy and secure integration with the industrial systems present. In this way, for example, the integrated 16-bit analogue output provides a signal proportional to the weight (0-20mA, 4-20mA, 0-10V, 0-5V selectable), which can be integrated in a PLC. Communication is via an RS-485 interface. The fast measuring rate of up to 600 measurements per second ensures a uniform analogue performance.

The WTM weighing indicator has a 6-digit, bright and easy-to-read display, which allows the weight value to be monitored directly in-situ. All of the settings can be conveniently adjusted via four operating keys. 
The weighing transmitter is designed for DIN rail mounting and can optionally be supplied with cable glands in the plastic housing.

Features of the weighing indicator
