Product Detail
Dew-Point Transmitter for Industrial Dryers - SF52Cost-Effective Moisture Measurement in Harsh Applications


Features

  • Ideal for OEM dryer use

  • Dew-point measurement range -40 to +60 °C (-40 to +140 °F)

  • Fast response

  • Rugged IP65 construction

  • 3-Point traceable calibration certificate

  • Accuracy ±2°C (±3.6°F)

  • Voltage or mA outputs

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.


Suitable Applications

  • OEM Industrial Dryers
