    CS451/CS456 Submersible Pressure Transducer 7.1.3 Appropriate Water Depth The CS451/CS456 must be installed below the water at a fixed depth. This depth should be chosen so the water pressure will never exceed the transducer’s pressure range (twice its pressure range).

    FIGURE 7-1. Transducer suspended with split mesh cable grip 7.2.2.3 Heyco Cable Grip To protect your transducer during deployment, Campbell Scientific offers the 31648 Heyco cable grip (FIGURE 7-2) to clamp the transducer to the submerged end of a 1-inch PVC pipe (FIGURE 7-3). The PVC pipe will help protect the sensor and cable from debris and disturbances while also providing a more secure means of anchoring the sensor to minimize movement.

    The A150 desiccated case allows the CS451/CS456 to be connected to the CWS900 wireless sensor and then used in a wireless network. FIGURE shows the CS451 wired to the A150’s terminal block. The 26972 cable is included with the A150.

  • Page 23: Programming

    The SDI12Recorder() measurement instruction programs CRBasic dataloggers (CR6, CR200(X)-series, CR800-series, CR1000, CR3000, and CR5000) to measure the CS451/CS456 sensor. This instruction sends a request to the sensor to make a measurement and then retrieves the measurement from the sensor. See Section 8.2, SDI-12 Commands , for more information.
