The EI-1034 is intended to be connected to a LabJack for 5 V power but can be used as a stand-alone temperature sensor when connected to a voltage measuring device and a power supply in the range of 5 to 30 volts.

It uses the highest grade available of the LM34 sensor from National Semiconductor with a typical room temperature accuracy of ±0.4 °F or ±0.25 °C.

The sensor is mounted in a stainless steel sheath and features a high-level linear output of 10 mV per °F and has an operating temperature range of 0 to +300 °F (-17 to +150 °C with U3/UE9 or -12 °C to 150 °C with U12).

The probe is suitable for air and liquid applications, and can be conveniently secured into pipes, vessels and chambers by using available ¼ inch compression fittings.

Please note the cable is only rated for -20 to 80 °C and can be used up to 100 °C.

Note: When operating at voltages less than 5 Volts the maximum operating temperature is reduced, typically at 4 Volts supply the maximum temperature limit is 200 °F

Power: +4 to 35 VDC at 90 uA

Output current: 10 mA
