The instruments of the HD2717T… series are transmitters, indicators, and ON/OFF regulators with data logging functions, they measure temperature and humidity.

The main feature of these instruments is their interchangeable probe. The probe can be replaced by the user without process interruption. Thus, the probe can be calibrated or repaired at a later time.
The instrument is available in different versions: with horizontal probe (S.TO), vertical probe (S.TV) or with remote probe (S.TC), having the probe connected to the electronics by means of a cable of various lengths.

The S.TO and S.TV probes are made of stainless steel AISI304, the S.TC probes can be of stainless steel AISI304 or plastic material.

The probe is factory calibrated and ready to use, it is provided with a SICRAM2 module which stores the calibration data of the probe, allowing the interchangeability of the probes.

The instruments measure:

• Temperature in Celsius or Fahrenheit temperature scale
• Relative humidity

and calculate:

• Absolute humidity
• Mixing Ratio
• Dew point

All models have both current and voltage outputs.
Some models are fitted with two control relays and one alarm relay, configurable by the user.
All models are fitted with a multistandard RS232/RS485 serial port and an auxiliary RS232C standard serial output. The RS485 serial output allows the management of more than one device in a network.

The data logger function allows to store the measures with a selectable storage interval.

Probes:

S.TV – Vertical probe L= 130mm, AISI 304

The material of the S.TC…probes can be chosen between stainless steel AISI304 or plastic material. (recognized by the letter P in the code)
