For that purpose all kind of temperature probes in 2-, 3-or 4-wire technology can be 140connected to the transmitter. Depending on application, measurement range and 131accuracy, different PT 100 / 1'000, Ni 1'000 or NTC probes in various designs 122 can be used. These can be plunge sensors, surface-, air-, liquid-, outdoor-sensors etc.. The TempMaxx converts the resistor signal to a standardised voltage and current signal (U & I) and shows the value on a big, clear LCDisplay. Additional functions such as alarm settings respectively definition of the working range and the possibility of a 2-point control, widen the field of applications. The necessitate digital output in the form of a relay contact is already integrated. The easy settings by the intuitive instrument menu is another advantage of this versatile measurement device. All setting parameters can be protected by a password. Thanks to the use of modern microprocessor technology and circuitry a high measurement accuracy, long term stability and flexibility is achieved. The robust and ergonomic plastic housing provides ideal installation options. TempMaxx, the instrument for accurate and flexible temperature measurement, monitoring and control. Made in Switzerland.
