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.
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
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
Continuous transmitter/sensor diagnostics.
Temperature compensation/calibration curves. Two levels of passcode protection provided;
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.
Complies with applicable NAMUR standards, and European EMC Directive 2004/108/EC.
Enclosure meets IP66 and NEMA 4X ratings.
