AMiR 7838 - 1

Infrared measuring technology • Compact, robust and precise infrared measuring heads. • Wide range of versions for applications in intelligent process control and monitoring systems, as well as in production and test lab. • Low cost standard version with fixed set temperature and output current range and emissivity can be manually set at the measuring head. • The standard version without programming functions is ideally suitable for connecting to ALMEMO® devices. • Measuring heads also available as addressable and remotely programmable versions. Accessories ALMEMO® connecting cable, 2 meters, ALMEMO® connector, programmed for the probe head’s temperature range, Sensor supply via ALMEMO® device (use of the device mains unit is recommended) (cable not suitable for ALMEMO® 4490-2, available here on request) for programmable measuring heads MR7838xP Protective window, snap-on, according to above lens detail Remote control set incl.

Infrared measuring technology HART® protocol: Single installation: Parallel working: Configuration examples: The Hart® protocol (´Highway Accessible Remote Transducer Protocol´) is one of the most popular intelligent field bus protocols. It is more often used in industry than any other protocol and is supported by a large number of products and software of other manufacturers. The Hart® signal combines the standard output of 4 to 20mA with a simultaneously running digital remote data transmission. As a result, the measuring heads can, additionally, digitally communicate through the...
