SENSOLUTION™ Model 762 - pH
pH Probe Assembly
The model 762 pH probe assembly is a loop-powered, isolated pH sensor, with all power being supplied from the two-wire current loop connection. The two-wire connection eliminates the requirement of a separate supply in addition to the loop supply voltage.
The model 762 pH probe assembly is a loop-powered, isolated pH sensor, with all power being supplied from the two-wire current loop connection. Isolation enables the probe to be at a potential relative to ground without affecting the integrity of the measurement. The two-wire connection eliminates the requirement of a separate supply in addition to the loop supply voltage.
Temperature-compensated pH or ORP measurement
Two-wire field mounted analyser – suitable for multiple-loop installations with a central controller
Local display of pH/ORP and temperature – suitable for use as a stand-alone pH monitor
Isolated 4-20mA signal
Simple pushbutton operation
Tough IP65 die-cast Aluminium enclosure
Plug and socket connectors for easy installation and maintenance
Tool-free operation – no dip-switches or potentiometers
Suitable for masthead mounting (as pictured) or wall mounting
With the inclusion of a pH800 analyser the Model 762 probe assembly and electrodes become a complete pH sensing unit. Theanalyser includes all the circuitry necessary for the measurement and transmission of an isolated 4-20mA linear signal.
The Model 762 assembly is manufactured from chemically resistant polypropylene and has spaces for two PG13.5 electrodes – a rugged glass pH electrode and glass temperature compensator. The reference is a double-junction arrangement with a large gel reservoir giving excellent stability in tough applications.
