NOTE:
The OS137A Series is a precision, miniature infrared transmitter. It measures
temperature via non-contact, and provides an analog output proportional to
the measured temperature. The OS137A Series is offered in three temperature
ranges: 0 to 100ºC (32 to 212ºF), -18 to 260ºC (0 to 500ºF) and -18 to 538ºC (0 to
1000ºF). The analog output is offered as 4 to 20 mA, 0 to 5 Vdc, 0 to 10 Vdc, 10
mV/degree C or F, or K type thermocouple.
The unit provides adjustable emissivity from 0.5 to 1.0, 10 to 1 optical field of
view, and field adjustable alarm output.
The super-compact design, 25.4 mm OD x 127 mm length (1.0” OD x 5.0” L)
is ideal to measure temperature in confined, and hard to reach places. The
Stainless Steel housing is NEMA-4 rated. The unit comes standard with a 1.82
m (6’) shielded cable.
