- Model EC-F3 - Galvanic Cell Type Oxygen Sensor


A galvanic cell type Oxygen sensor that exhibits exceptionally long life plus excellent chemical durability. The Manning EC-F3 exhibits excellent accuracy and precision, with negligible response to common interference gases and dramatic changes in relative humidity.

In the past, Oxygen sensors have been prone to be short lived and, at times, erratic. The Manning EC-F3 Oxygen sensor utilises a larger supply of electrolyte that is formulated to be minimally affected by interference gases, even Carbon Dioxide (CO2). The sensor is also temperature compensated.

The standard O2 sensor is housed in a rugged #16 gauge, NEMA 1 design steel enclosure. An optional bargraph readout, which will provide a downscale alarm, can be mounted inside the enclosure.The transmitter/ pre-amp provides a linear 4/20 mA current signal out in two ranges: 0-25% or 15-25%.

The Oxygen sensor is boardmounted and easily replaceable. The transmitter/pre-amp has been designed with EMI and RFI filtering and shielding.
