Operating Environment
This device is intended for use in engine coolant and air cooled applications
and shall withstand such an under hood environment.
Normal Operating Temperature: -40°C ~ 135°C (continuously).
Relative Humidity: 0 to 100% RH.
Typical Pressure: When installed at the minimum torque the sensor shall be
capable of sealing engine coolant with a positive pressure of 206.8 kPa (30 psi)
at 135°C applied to the probe tip end of the sensor.
Extreme Operating Environment: Maximum temperature excursion to 150°C for
1 hour.
3.18.4.5
Storage Environment
Storage temperature: -40°C to 120°C for an indefinite duration
Transport at altitudes to: 13,700 m for an indefinite duration
E l e c t r i c a l Enviro nmen t
Typical Voltage: The sensor circuit operates with a DC voltage reference of 5 ±
0.1 VDC.
Maximum Excitation Current: The sensor calibration shall not be affected by a
current source of less than 1 mA at all temperatures.
3.18.4.6
Sample Cleaning
When necessary the samples may be cleaned in isopropyl alcohol for one
minute with mating connectors in place and then air-dried
