Output Voltage: ±5.0 V
Temperature Range: -65 to +250 °F (-54 to +121 °C)
Housing Material: Stainless Steel

Specification Notes

[1] High frequency response may be limited by supply current and output cable length.
[2] Tested using voltage source and input capacitor equal to the feedback capacitor, to simulate a charge output sensor.
[3] Effective feedback resistance for time constant is 3 times tested value due to circuitry (i.e 1x10E9 = 3x10E9 ohm)
[4] See PCB Declaration of Conformance PS024 for details. A low impendance connection from case to earth ground is required to maintain CE compliance.
