The SF52 dew-point transmitter is a simple, cost effective
sensor designed for use in harsh industrial dryer applications
where reliability and toughness are required at an economical
cost.
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 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.
