    1.1 Description Multi-function instrument The Honeywell 9782 Conductivity/Resistivity Analyzer/Controller (Figure 1-1) is a microprocessor-based instrument for analysis of conductivity, resistivity, total dissolved solids, or concentration in industrial processes. The resolution for all measurements is +/- 0.5% of reading (except for temperature; see below). The units of measure are:...

  • Page 16: Input

    Conductivity/Resistivity Analyzer/Controller Input Input to the 9782 can be from any Honeywell conductivity cell at distances up to 1500 feet. Outputs Optional isolated 0 to 1 V, 0 to 10 V and 4 to 20 mA outputs are available. Use these analog outputs for retransmission of process variables, or for Current Adjusting Type control using an output signal that is directly proportional to the input (see 1.5.3).

Similarly, if a junction box is used to extend the leads up to 150 feet, no compensation is required. However, if longer leads are used (greater than 150 feet), signal quality can be adversely affected unless you enter information that will permit the 9782 to compensate for lead resistance.
