Sensors with relay outputs E'lemer ELEMER-AIR-30M

The sensors are designed for continuous conversion into a unified current output signal and/or a digital signal in the standard of the HART protocol of input measured values.

The device has not only very wide measurement ranges (for example, for overpressure from 0.04 kPa to 60 MPa), but also the possibility of reconfiguring ranges with a coefficient up to 1:60. This allows for high-precision measurements with basic error values of 0.1%. The output signal of the converter is a unified current 4...20 mA or a combined 4...20/0...5 mA. In the "HART" version, the converter also generates the corresponding frequency-modulated signal.

The sensors are equipped with a multifunctional 4-digit LCD indicator with backlight and a graphic scale. The sensors have a modular structure: a sensor module and an electronics module. All modules of the same type are interchangeable. This ensures high maintainability of the sensor. All sensors are protected by a two-level password against unauthorized access. The sensor parameters are configured using an external or internal keyboard or via the HART protocol.

Alarm and control devices (2 electromechanical or optorele) are built into the converter, which greatly simplifies the use of the device in automated control systems.
