2.1 Device description

The sensor is designed to measure the oxidation reduction potential (ORP) in liquids. It has a
connection for a 4...20 mA current output with HART

communication.

The connection is designed as a plug connector and at the same time supplies the sensor with
power.

The PG 13.5 thread is used as process connection.

VP2 connector

Nickel-plated brass body

PG 13.5 thread

Washer

O-ring

Glass shaft

Diaphragm

Platinum electrode
