Description
The converters are equipped with two relay outputs for signaling, indication, or control of external devices, discrete inputs, an external probe with a cable length of 1, 2, 4 m, designed for measurement in an environment with pressure up to 2.5 MPa. Delay settings, hysteresis, and sound signal are included for each relay. Parameters are easily adjustable using a computer or the keyboard on the sensor's front panel. The converter is controlled by a microprocessor housed in a durable plastic case with connection terminals. A large two-line LCD display is designed to simultaneously show two parameters. If necessary, the display can be turned off.
Recently, temperature and humidity levels have been considered as the most important parameters responsible for indoor climate quality. Especially in buildings and rooms with large gatherings of people, such as conference halls, hospitals, schools, cinemas, theaters, and wellness centers.
With the help of such sensors, engineers, environmental experts, and healthcare specialists can optimize ventilation to create a comfortable and «Healthy» indoor climate.
ATTENTION, the device is currently discontinued.
