  • Description

  • General

  • External sensors

Wireless data logger for sensors
with 4–20mA output

This tempmate.®-R radio data logger (LGS34) can be connected to a sensor with standard 4–20mA output. The sensor’s measurements can be transmitted by the logger, but depending on the product variant, the sensor can also be supplied with power. The measurements are transmitted directly to a PC, where they are then displayed. The measurement data is transmitted live by radio to the monitoring workstation, or is stored in the data logger until it is called up wirelessly.

Interfaces for the following sensors

  • Movement
  • Pressure
  • Fill level
  • Gas
