Rotronic transmitters

Published: 12-Mar-2003


The three model M-Series humidity/temperature transmitters from Rotronic uses digital signal processing with the HygroClip probe and a new custom designed ASIC chip.

The M1 is a basic transmitter with fixed probes for wall and duct installation and incorporates an integral digital interface to which a hand-held device can be connected for test and calibration functions. M2 is similar, but has the ability to interchange probes, either to simplify maintenance/calibration or to change application. The M3 incorporates a number of options. The standard measured values of %rh and °C can be converted into different humidity parameters such as dewpoint or enthalpy and then output as an analogue signal in combination with either %rh or °C. Data can be transmitted using a serial output or via radio communication. Both protocols can be combined onto a monitoring/ control network. All three measure over the full 0 -100%rh range and temperature measurement covers -40°C to +85°C.

In regulated manufacturing, monitoring environmental conditions and critical equipment is essential to protect product quality, yield, and patient safety. Facilities often use a Facility Monitoring System (FMS) to track factors like airborne particles, temperature, and humidity. Beyond regulatory compliance, FMS delivers real business value through reduced waste, improved yield, higher quality, and greater profitability
