The CS500 was a modified version of Vaisala's 50Y Humitter. The probe measured temperature with a 1000 Ohm platinum resistance thermometer (PRT) and relative humidity (RH) with a 50Y Intercap humidity sensor. The CS500 was cabled with our pn 9720 cable.

The "-L" on a product model indicates that the cable length is specified at the time of order.



  • ±3% (over 10 to 90% RH)
  • ±6% (over 90 to 100% RH)
Operating Temperature Range -40° to +60°C
Diameter 1.2 cm (0.47 in.)

Weight 0.05 kg (0.1 lb) with 1.83-m (6-ft) cable



The CS500 is typically housed in a 41303-5A 6-plate naturally aspirated shield.

It may also be housed in a 41003-5 10-plate shield if additional hardware is used. A 41322 Adapter Plate allows the HMP50 to be mounted in the lower part of the 41003-5 10-plate shield. Alternatively, a 41381 extension tube and the 6637 split nut plug can be used to mount the CS500 in a higher part of the 41003-5; the pn 41381 cable is also required.

Both the 41303-5A and the 41003-5 attach to a crossarm, mast, or user-supplied pipe with a 1.0-in. to 2.1-in. outer diameter.
