Dew-Point Transmitter for Industrial Dryers - SF52Cost-Effective Moisture Measurement in Harsh Applications
Features
The SF52 dew-point transmitter is a simple, cost effective moisture sensor designed for use in harsh industrial dryer applications. It is reliable and tough enough to withstand the high temperatures often associated with industrial drying.
The SF52 is available with a choice of G1/2” and 1/2” NPT process connections and voltage or mA outputs. A key feature of the unit is the recessed and protected measuring element giving an extended sensor life cycle.
Our polymer-based moisture sensor is calibrated on a high volume traceable calibration system, providing OEM quantities of units on short deliveries, each with a 3-point calibration certificate.
