Si-PRO-U-I-100-H

For demanding processes and climate control applications
The Si-PRO-U-I-100-H is an interchangeable, heated hygrometry probe for Si-C320 transmitters and it has been designed for being used in environments where there is constant high humidity or rapid oscillanting humidity where the probe’s performance and its tolerance to pollutants are key.

Description

Stainless steel body and sintered filter. Length 100 mm (3.94’’), Ø 13 mm (0.51’’).

It provides the dew point and freezing point as a measurement. The relative humidity value, as well as other psychrometric values, can be calculated when the Si-PRO-T-150 temperature probe or a Pt100 probe is connected to the Si-C320 sensor-transmitter using the Si-ACCETP adapter.

Main applications: industrial processes, air handling units, drying processes, pharmaceutical production.

The Si-ACC-R2 cable is required for connection to Class 320 sensors-transmitters.

  • Heated probe, minimizes condensation on the sensor
  • High accuracy and long-term stability
  • Pollution resistant
  • Detachable probe cable for easy installation
