Carel Pressure Sensor SPK
Carel type P pressure sensors are cost-effective, highly accurate products that use piezoresistive technology, with a 0.5-4.5 ratiometric output and brass housing. Excellent EMC features make these sensors suitable for the harshest environments. These sensors can be directly installed on the refrigerant pipe (no capillary tube is needed) Compatible with the most common refrigerants. This series is excluded from the scope of the Pressure Equipment Directive 2014/68/EU (the sensor itself does not have safety function). The sensors are equipped with aesthetic o-rings to recognise the pressure range easily.
