HD2817T… Transmitter, indicator, ON/OFF regulator, temperature and humidity datalogger.
The HD2817T... series instruments are transmitters, indicators, ON/OFF regulators with datalogger function. They measure temperature and humidity. They are fitted with an LCD backlit graphic display 128x64 pixel. The main characteristic of these instruments is the interchangeable probe. The user can virtually change the probe without interrupting the process. Then the probe can be calibrated or repaired.

We have models with horizontal (S.TO), vertical (S.TV) or separate (S.TC) probes, connected to the instrument using cables of different lengths. The S.TO and S.TV probes are made of AISI304 steel, the S.TC probes can be made of AISI304 steel or POCAN plastic material. To measure the dew point in compressed air systems, the probe S.TC2.480.2 can be connected to the HD2817T...
The probe, factory calibrated and ready for use, is fitted with a SICRAM2 module storing its calibration information and allowing its interchangeability.

The devices measure:
  • Temperature in Celsius or Fahrenheit degrees
  • Relative humidity
and calculate:
  • Absolute humidity
  • Mixing ratio
  • Dew point
  • Wet bulb temperature
All models are fitted with current or voltage analogue outputs. We supply models with two working relays and an alarm relay, user configurable. All models have a multistandard RS232/RS485 output and an auxiliary RS232C serial output. You can connect several network devices through the RS485 serial port. The HD2817T... models use a wide LCD backlit graphic display (128x64 pixel) showing three physical quantities simultaneously or a real time graph of any of the measured quantities.

The datalogger function allows recording of the measurements detected by the instrument, according to a frequency set by the user. The instrument configuration is permanently stored. The internal clock is protected against a mains power failure by a special Lithium battery. When making the order, you can select the power supply between 24Vac/dc or universal 90...240Vac.
