CS451/CS456 Submersible Pressure Transducer

FIGURE 5-1. CS451 nose cone options

6. Specifications

Features:

x Output acceptable for recording devices with SDI-12 or RS-232

capability including Campbell Scientific dataloggers

x Quality construction that ensures product reliability

x Rugged stainless steel or titanium case that protects piezoresistive

sensor

x Fully temperature compensated

x Low power sleep state between measurements that reduces power

consumption

x Weighted nose cone offered that adds 0.2 kg (7.4 oz) to the

transducer’s weight. Additional weight makes submersion of the

transducer easier
