The Products

Si-C320
Industry – Laboratories
- Supplied with adjusting certificate
- 2 inputs for probes
- 1 input for internal differential pressure sensor
For clean rooms, regulated environments and industrial VAC applications where a perfect regulation/monitoring of the air parameters is needed, our Si-C320 transmitters provide reliable measurements and allow achieving compliance with the strictest regulations.

Si-CPE320
Clean Room Special
- Supplied with adjusting certificate
- Auto-calibration solenoid valve
- 1 input for external probes
For clean room applications, the Si-CPE320 transmitter is flush mountable to avoid disturbing the working environment. It is equipped with a high-grade stainless-steel waterproof front panel with an integrated touch screen. Equipped with the same technologies as the Si-C320, this panel-mounted version provides state-of-the-art reliability and accuracy.

Si-ATE320
Multifunction flush-mounted display
- Display of 1 to 3 parameters
- Graphic touch display
- Visual and audio alarms
This flush-mounted display allows you to view and relay measurements from three transmitters. It features a high-quality stainless steel front panel and color touchscreen, all made of materials that are fully resistant to cleaning with vaporized hydrogen peroxide (H2O2). The Si-ATE320 fits perfectly into the aeraulic management system of a cleanroom environment, without intruding on its occupants' space.
