HD2717T... - models for vertical (S.TV) or remote probe (S.TC)
General information:
The instruments of the HD2717T... series are transducers, 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). For the measurement of dew point in compressed air systems, the S.TC2.480.2 probe can be used. 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 its interchangeability. The instruments measure:
- temperature in Celsius or Fahrenheit
- relative humidity
and calculate:
- absolute humidity
- mixing ratio
- dew point
- wet bulb temperature
All models have both current and voltage outputs. Some models are fi tted with two control relays and one alarm relay, confi gurable by the user. All models are fi tted 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 fi rst 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 measuring values 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 24 V AC/DC or universal 90 to 240 V AC.
Probes are supplied with filter P7 as standard. For temperatures up to 150°C we recommend the use of probes with stainless steel (AISI 304) stem and filter P6.
Extra charge for replacement of filter P7 with P6.
