PT4194 (Oil) - Melt pressure sensor with mineral filler and mounting connection 1 / 2-20UNF

PT 4194 (Oil) 4-20mA

PT4194 sensors provide an industry standard 4-20 mA amplified signal designed to work with DCS and PLC. It is a sensor with ± 0.5% accuracy ideal for the food or pharmaceutical industry requiring easy installation, repeatability and reliability. It is filled with mineral oil that meets the requirements of FDA 21 CFR 178.3620, 21 CFR 172.878 and 21 CFR 573.680.

The PT4194 is equipped with a new automatic zero calibration function. Auto-Zero gives the user the ability to install the sensor right out of the box and perform a calibration at the touch of a button. Combined constructions with thermal thermocouple or RTD are also available. The PT4194 comes with a 1 / 2-20 UNF mounting thread for simple and easy installation for standard mounting holes.
