GfG Instrumentation 2220032 EC22 O Series Fixed Transmitter, No Display, (Base Unit without Sensor), Modbus

Transmitter for oxygen measurement with partial pressure sensor

If you need to monitor oxygen in applications with high helium concentrations, that would influence other oxygen sensors' results, the EC22 O transmitter is a reliable and economical solution. The EC22 O transmits measured values and status notifications via digital (RS-485) signal. In combination with GfG's reliable controllers, it can be installed in new gas detection systems or retrofitted into existing ones.

The EC22 O uses the electrochemical method (EC) to detect oxygen. The long-life partial pressure sensor measures the oxygen concentrations in a measuring range of 0 to 25 vol % with total accuracy, even in air containing helium. Its accurate measurement is made possible by the automatic temperature compensation and the linearization of the measurement signals.

Device protection

The housing is protected against the ingress of dust and water (protection class: IP54).

Communication and service

Signals are transmitted via the digital RS-485 interface (Modbus protocol). The EC22 O uses two status LEDs to indicate its operating status. The RC22 remote control facilitates service and adjustments on site (one-person adjustment). Test gas for function tests can be inserted using a flow adapter.
