Originally developed for demanding under-hood automotive environments, the PT sensor is made to withstand the rigors of today's applications. Pressure: The pressure transducer is a 0-5 Vdc output design that requires no end-user amplification. Similar to other TI pressure transducers, the voltage output is ratiometric to supply voltage. With a data conversion circuit referenced to supply voltage, accuracy can be maintained regardless of supply voltage variation. Temperature: The temperature sensor is an NTC thermistor (resistance decreases with increasing temperature) with either 10K or 100K value @ 25oC. Unlike other integrat- ed packages, TI's PT sensor places the thermistor directly in the measurement medium (fluid stream), which provides a 50% faster response time and greater accuracy over encased or pipe- mounted thermistors. Packaged with an AMP Micro-Quadlok SystemTM connector, the sensor has a steel or brass housing, and is available in two standard pressure ranges: 0-150 or 0-500psi with a variety of pressure fittings.
