SF52 Dew Point Transmitter 05570

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.

• Ideal for OEM dryer use
• Dew-point measurement range -40 to +60°C (-40 to +140°F)
• Fast response
• Rugged IP65 construction
