OS137 Series Miniature Non-Contact Infrared Temperature Sensor/Transmitter iii CAUTION & SAFETY INFORMA TION If the equipment is used in a manner not specified in this manual, the protection provided by the equipment may be impair ed. The Installation category is one (1).
1 SECTION 1 - INTRODUCTION The OS137 Series is a precision, miniatur e infrared transmitter . It measures temperature via non-contact, and pr ovides an analog output proportional to the measured temperatur e.
2 2 - ** means: -MA : 4 to 20 mA current output -V1 : 0 to 5 Vdc output -V2 : 0 to 10 Vdc output -K : K type thermocouple output -MVC : 10 mV/ºC output -MVF : 10 mV/ºF output The following table lists the optional accessories: 2.2 – Electrical Connection The shielded cable provides the power and output connections.
3 Operation 3 SECTION 3 – OPERA TION 3.1 – Measuring T emperature Before starting to measur e temperature, make sure the following check list is met: The power and output connections are made (Fig 2-1). The target is lar ger than the optical field of view of the transmitter (Fig 3-1).
Operation 3 4 3.2 – Ambient T emperature The transmitter can operate in an ambient temperature of 0 to 70°C (32 to 158°F) without any water cool jacket. It can operate from 0 to 200°C (32 to 392°F) with the water cool jacket accessory , OS137-WC (Fig 3-6 & 3-7).
