2 Description

The miniature infrared sensors MI are noncontact infrared temperature measurement systems. They accurately and repeat ably measure the amount of energy emitted from an object and convert that energy into a temperature signal.

The following outputs are available:

J‐Thermocouple

K‐Thermocouple

0 ‐ 5 Volt

0 ‐ 20 mA or 4 ‐ 20 mA

10 mV / °C head ambient temperature signal

RS232 interface

optional: RS485 interface

The sensing head is protected by a rugged IEC 529 (IP 65, NEMA‐4) stainless steel housing, and is connected to the electronic box with a 1 m (3 ft) cable. Longer cables must be ordered as an option. The electronic box is separated from the sensing head. This allows the sensing head to be used in hot environments up to 180°C (356°F) without cooling. The electronic box can only be used in ambient temperatures up to 65°C (150°F).

MI will allow sensing heads to be interchanged by programming in the unique calibration data associated with different heads. Take special care for the sensing head calibration data printed on the cable!
