112CP PT Series Combined Pressure and Temperature Sensor Standards

•	AMP 4–pin MQS connector
•	±2.0% for roughly 100°C span
•	Pressure is a voltage output (0–5Vdc); Temperature is a NTC resistance output (1h–1M ohms)
•	Internal seal: neoprene (good for most refrigerants at least to about 120°C)
•	These are sealed gauge devices (psig = psis at sea level, psig = psia – 14.7 at sea level)
•	If require your part number marked or non–standard pressures/threads, please see data sheet (PDF) for the Sensata Technologies custom part number

*	Transfer functions for both HPT and PT above are based on 5.00Vdc input. Output is ratiometric to input; i.e., if supply voltage drops 2% to 4.9V, output will drop 2%. Thus, to maintain accuracy with less regulated power, "Vout" should be substituted with "Vout*(5/Vin)".
**	12mm x 1.25 straight male threads/mm, requiring an external O–ring and groove around mating surface
***	Standard Siemens NTC thermisters: 10kohm@25°C = 94kohm@-20°C, 0.4kohm@120°C
***	100kohm@25°C = 1098kohm@-20°C, 2.6kohm@120°C (see R vs. T table and plot on our website for more detail)
