Description
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 three 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 POCAN (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 models HD2717T... can be with or without LCD. The display shows on the first
line the relative humidity or a derived parameter and on the second line the temperature
in degrees Celsius or Fahrenheit.
The data logger function allows to store the measures with a selectable storage
interval.
The instrument setup remains permanently stored, while the real time clock is protected
by an apposite Lithium battery against temporary mains voltage interruptions.
The power supply can be chosen, at the time of placing the order, between 24Vac/
dc or universal 90...240Vac.
