The product was created from the need to control the temperature and humidity in electrical panels with particular attention to costs. The THM-1A detects the temperature and humidity at the installation point, digitally encodes the signals and makes them available to be read by a programmable unit (for example the PLC) simply by connecting a digital input.
Thanks to a simple binary data transmission, with coding as per protocol
opposite, it is possible to measure the temperature and humidity at the installation point of the THM-1A.
In this way it is possible to monitor, in real-time (with update every 25 seconds), the read values, which can be processed according to your own
Control cooling or heating systems with a simple operation data comparison and PLC command (or programmable unit in general), generate pre-warnings and alarms to alert the operator of the presence of dirty filters, malfunction of anti-condensation systems or simply report an anomaly are just some of the main potential of THM-1A. Functions they are in fact multiple and each has the ability to manage the data detected as believe better, according to individual needs.
