The 7501 is a field-mounted, Ex d explosion- and flame-proof temperature transmitter with local operator interface for easy programming, review and diagnostics of process values in the field. The optical buttons combined with the 10-mm explosion-proof window is a patent-pending technology. The optical buttons are immune to interference of ambient light sources and false triggering caused by shadows and reflections, and the device dynamically adapts to accumulation of dust and moisture, says the company. The user can also perform advanced HART programming from the front, and as a result, significantly reduce the need for handheld communicators. The transmitter delivers HART 7 functionality with HART 5 compatibility and can be configured to measure two-, three- and four-wire RTDs and 13 different thermocouple types, as well as bipolar millivolt and resistance signals, and it provides an analog output. — PR electronics A/S, Roende, Denmark
