Environmental/Process Air Transmitters - 1

RH and Temperature with Dew Point or Pressure Outputs HX80A Series NIST Standard HX85A shown smaller than actual size. U 316 SS Housing U ±1% RH Accuracy U 0.5°C (1.0°F) ± Temperature Accuracy U High Temperature [120°C (248°F)] U emovable Stainless R Steel Sensor Cap U RS232 Standard U djustable ¾ NPT A Fitting The HX80A Series is a family of humidity probes that offer a variety of measurement parameters with precision accuracy: relative humidity and temperature, with dew point or pressure. The probe is easily adaptable for most applications via a 3⁄4 NPT fitting that can be adjusted to any desired position, including high temperature and high pressure conditions. This remote type transmitter comes standard with a 1.8 m (6') cable and is ideally suited for many different applications such as environmental chambers, compressed air, and industrial applications. Models offer a stainless steel probe with a removable sinter stainless steel filter and RS232 (which allows for reading of data, scaling output, and for HX86A type units, changing the digital display and setting the alarms). All models have 3 outputs, with output 1 scaled for 0 to 100% RH, output 2 scaled for -20 to 120°C (-4 to 248°F), and output 3 determined by the model number. Output 3 for HX85A and HX86A is -60 to 40°C (-76 to 104°F) dew point, for HX85BA and HX86BA is 750 to 1100 mb, and for HX85PA and HX86PA is 0 to 200 psia. RH measurement range is 5 to 95% with an accuracy of ±1%. temperature accuracy is ±0.5°C (33°F). HX85A (probe only) models (HX85A, HX85BA, HX85PA) offer 0 to 10V signals on the outputs via a 1.8 m (6') cable. The HX86A models (HX86A, HX86BA, HX86PA) include a display box attached to the end of the cable from the probe, and offers a 2 line digital display, 2 alarms, three 4 to 20 mA output signals, and an RS232 serial output. Hu-1 SPECIFICATIONS RH Accuracy: ±1% RH RH Measurement Range: 5 to 95% Time Constant: <15 sec, air flow dependent (for 66.6% response) Temp Accuracy: ±0.5ºC (1.0°F) Temp Measurement Range: -20 to 120ºC (-4 to 248ºF) Pressure Rating: 317 kg (700 lb) (47.6 bar) max Serial Output: RS232C (bi-directional) to DTE device, 19.2 kilo baud, 8 bits data, 1 stop bit, no parity Power Requirements: 18 to 30 Vdc un
