HD2717T Series – Interchangeable Probe Active Transmitters
Brand: Delta OHM S.R.L.
The instruments of the HD2717T and HD2817T series are transmitters, indicators, and ON/OFF regulators with data logging functions; they measure temperature and humidity.
The models of the HD2817T are fitted with a graphic 128 x 64 backlit display.
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 Technopolymer PBT (plastic material).
To both series, it is possible to connect the S.TC2.480.2 probe for the measurement of humidity and dew point in compressed air systems, or the S.481.2 probe for the measurement of temperature and humidity in pipes.
The probes are factory calibrated and ready to use, they are provided with a SICRAM2 module which stores the calibration data of the probes, allowing their interchangeability.
The instruments measure
- Temperature in Celsius or Fahrenheit scales
- Relative humidity
And calculate
- Absolute humidity
- Mixing Ratio
- Dew point
- Wet bulb temperature
