Technical content

Submersible Pressure Transducers Campbell Scientifi c’s CS450 and CS455 submersible pressure transducers provide reliable, accurate pressure and tempera- ture measurements. Th eir rugged construction makes them suitable for water level measurements in canals, wells, ponds, harbors, lakes, streams and tanks. An NPT fi tting allows the CS450 and CS455 to be used in closed-pipe applications. Both transducers output either a digital SDI-12 or RS-232 signal to indicate observed pressure and temperature. Th is output is acceptable for recording devices with SDI-12 or RS-232 capability including Campbell Scientifi c dataloggers. Th e transducers consist of a piezoresistive sensor and a temperature sensor housed in a metal case. Th e CS450 has a 316L stainless-steel case that can be submerged in most canals, wells, ponds, lakes, and streams. Th e CS455 has a rugged titanium case that allows it to be used in saltwater or other harsh environments. Th e CS450 and CS455 are fi tted with a rugged Hytrel cable that remains fl exible, even under harsh environmental con- ditions. Th e cable incorporates a vent tube to compensate for atmospheric pressure fl uctuations. Th e vent tube termi- nates inside a desiccant tube, which prevents water vapor from entering the inner cavity of the transducer. Campbell Scientifi c off ers the A150 Desiccated Case that allows the CS450 or CS455 to be connected to a CWS900 Wireless Sensor Interface (for use in a wireless sensor network) or to be connected to a prewired enclosure (see Ordering Information on page 2). Features/Benefi ts

  • Output acceptable for recording devices with SDI-12 or RS-232 capability including Campbell Scientific dataloggers.
  • Static accuracies of ±0.1% FS and ±0.05% FS* avail- able. Accuracies are over 0° to 60°C range.
  • Quality construction that ensures product reliability.
  • Rugged stainless steel or titanium case that protects piezoresistive sensor.
  • Quick shipment aft er receipt of order (ARO).
  • Fully temperature compensated.
  • 24-bit A/D.
  • Simultaneous 50/60 Hz rejection.
  • Low power sleep state between measurements that reduces power consumption.
  • Weighted nose cone offered that adds 0.465 lbs (0.211 kg) to the transducer’s weight. Additional weight makes submersion of the transducer easier. Questions • Research • Pricing www.campbellsci.com/cs450 www.campbellsci.com/cs455
