876pH INTELLIGENT TRANSMITTER FOR pH AND ORP FOXBORO

The Foxboro® brand Model 876PH is a 2-wire loop powered intelligent transmitter that, when used with appropriate electrochemical sensors, provides measurement, local display, and transmission of pH, ORP (Oxidation-Reduction Potential), or ISE (Ion Selective Electrode) concentration. The transmitter outputs a HART digital signal and a 4 to 20 mA analog output. Versions are available for use with both analog and Smart (digital) sensors.

FEATURES

•   Either single sensor input (pH, ORP, or ISE), or dual sensor input sensor (simultaneous pH and ORP).

•   4 to 20 mA output with a HART(1) digital signal.

•   Remote configuration/calibration with the HART

  hand-held communicator or PC-based

  configurator.

•   Local configuration with the keypad on the

  integral local human interface.

•   LCD indicator can display either one, two, or

  three measurement variables.

•   Versions are available for use with both analog

  and Smart (digital) sensors.

•   Input and Output Communications model code

  selection S (876PH-S) supports the PH10-*S Smart (digital) pH sensor and a real-time clock (RTC) function with power reserve.

•   Fault isolation to transmitter or sensor.

  1. Usable with HART Versions 5, 6, and 7.

 Galvanically isolated output.
 High impedance inputs for glass and reference electrodes.

 Approved/Certified as intrinsically safe device

for use in hazardous area locations.
 Field Device Tool (FTD) certified DTM (Device

Type Manager).
 Continuous transmitter/sensor diagnostics.
 Temperature compensation/calibration curves.  Two levels of passcode protection provided;

configurable.
 Analog sensor input version is compatible wit h all Foxboro pH, ORP, and ISE sensors, and many non-Foxboro sensors. Smart transmitter is compatible with PH10-*S sensor.
