Everything about autosen


The electronic pressure sensor AP203 was designed for use in the industrial process industry. The sensor has a fixed measuring range of 0 ... 25 bar. The device is equipped with an analogue output, a G1/2 male process connection (according to DIN EN ISO 1179-2) and an M12 connector.

The flush-mounted design of the ceramic-capacitive measuring cell enables use in pasty and contaminated media - e.g. glue, paint, foam or sludge. These media harden in the dead spaces of transmitters without a flush diaphragm and block the process connection.

A high temperature resistance as well as the compact and robust stainless steel housing with protection class IP67 allow the use in harsh environments. In addition, the sensor is characterised by very good repeatability, low characteristic curve deviation and a cost-optimal price-performance ratio.
