* High-end digital sensor for atmospheric pressure (P.)and humidity (RH) and air temperature (T) with protective ler (ABS material, 1mm gap width and 0.15mm stainless steel mesh)
* Probe integrated into the housing, on the wire or on the stainless steel tube
* 2 current outputs 4÷20mA (2-wire with current loop power supply) or 2 voltage outputs 0÷10V (3-wire) or RS485 interface
* For analog outputs, possible connection with any measured value
* Programmable ranges of processing measured values
* LCD display with keyboard (optional) for viewing measurements and configuration
of parameters
* Parameters configuration from the keyboard via RS485 or PR port (AR956 or AR955
programmer) and a free ARsoft-CFG computer program that allows to quickly set and copy all configuration parameters
* High stability of measurements
* Protection level IP65 ensured by the housing, increasing work reliability thanks to
high resistance to the penetration of water and dust as well as surface condensation
of water vapor inside the device, IP40 probe (the measuring probe is not resistant to
Rooding or ondensation of water vapor inside it)
* Calculation of dew/frost point [°C], absolute humidity [g/m3] (calculation for atmospheric pressure 1013 hPa) with the possibility of linking the calculated values to an analog output
* For the transducer with RS485 all measurements and calculated values available for reading in the register map MODBUS
