AST47PT

Stainless Steel Media Isolated Pressure / Temperature Sensor with Twin 4-20mA Loops

AST47PT Pressure TemperatureTransmitter product photo

The AST47PT is the sensor solution for monitoring pressure and temperature with one device. With twin, 4-20mA loop-powered output signals, the AST47PT provides accurate pressure and temperature outputs for measurements of liquids and gases. Packaged with all stainless steel wetted materials and the base of AST’s Krystal BondTM Technology, this pressure-temperature sensor is constructed to perform in harsh environments and high cycle applications. The AST47PT is available with pressure ranges up to 500 PSI and a temperature measurement range of -40° to 85° C.
