Product Description
The SF72 dew-point transmitter is a compact sensor designed for use in industrial dryer applications at the key -80 to +20°C dp measuring points, where response speed, reliability and long term stability of data within a control process is critical.
The transmitter is pressure rated to 450 bar, ensuring process gas safety, through the use of a 10-year fi eld-proven stainless steel body and glass-to-metal seal. The SF72 has three alternative industry-standard sample block connections giving form, fi t & function benefi ts.
Our polymer based sensor is calibrated on a high volume traceable calibration system, providing OEM quantities of units, each with an 8-point traceable calibration certifi cate.
