KELLER Series 21C Pressure Transmitter

Product Description

The pressure transmitters of the 21C series with ratiometric 0,5...4,5V output combine chip-in-oil measuring cells with conventional electrical connections and pressure connections, making them ideal for industrial use. The transmitters are extremely resistant to environmental influences and deliver accurate measurement results over a temperature range of -40 °C to 125 °C.

The C-series transmitters are noted for their ability to deliver high accuracy over a wide temperature range. This is achieved by means of mathematical modelling of the sensor characteristics and digital compensation. In order to do this, each transmitter is gauged over pressure and temperature, programmed and checked after calibration in the same test set-up. The modular design of the Series 21C and the extensive vertical range of in-house manufacture provide a high degree of flexibility. The company can quickly adapt to customer requests, even with large production batches. The extensive standard range of connectors and pressure connections means that a CIO measuring cell (Chip-in-Oil) can be quickly welded in from stock if small numbers are involved, and then calibrated to the required temperature range. RoHS conformity and comprehensive EMC protection are a matter of course, therefore qualifying the Series 21C for use in industrial areas.
