Pressure Measurement

Researchers studying the habits of sea mammals such as dolphins, seals and whales need to know the depth to which these animals dive. Omni Instruments supplies small, low cost pressure transducers which are used in data loggers attached to whales and dolphins to measure the depth to which they are diving. These sensors are highly accurate, and have the added advantage that they draw very little current, which is important in battery powered applications.

Downhole tools used in oil and gas drilling and exploration require high performance sensors for pressure measurement. Our series 8 and series 10 OEM pressure capsules are available in ranges up to 1000 bar. They are suitable for operating temperatures up to 150 degrees C, and will provide a 200mV full scale output using a 1mA constant current supply.

A nuclear power station required to measure pressure upstream and downstream of restrictors and in the transfer line of a sludge outflow possibly containing radioactive materials. Omni Instruments provided a special sensor with a design that entails no fluid fill of the sensor, and no possibility of fluid travelling up the cable, permanently submersible to 6m.
