The Series 629C Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability.

Micatrone's flow sensor MFS-SS has been developed to meet the great demand for accurate air flow measurement in all types of air-handling systems. The MFS-SS is based on the principle of averaging the velocity profile over the height or the diameter of the duct.

The Finetek SD series optical level detection operates on the principle of reflection of light in a prism. If the sensor is surrounded by air, the light beam will be reflected on the sensor wall, and when it is surrounded by liquid, the light beam will be interrupted. The sensor thus detects a liquid level without any moving parts. It is a simple and robust solution for applications in for exam...

A reliable and accurate portable instrument for measuring pressure and differential pressure. Standard functions are: min, max, hold, self-calibration, adjustable automatic shut-off and backlight. Each instrument is supllied with a transport case, tubing, calibration certificate (model E) or adjusting certificat (model S).

The Dwyer GSTA series is a carbon monoxide (CO) transmitter for room or channel mounting. The GSTA series can be selected with and without display and has a 0-10 V or 4-20 mA output. Optionally there is an implementation with Modbus or BACnet communication.
