SENSOLUTION™ Model 762 - Fluoride

The model 762 fluoride probe assembly is a loop-powered, isolated fluoride 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.

Features:

• Temperature-compensated measurement

• Two-wire field mounted analyser – suitable for multiple-loop installations with a central controller

• 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

With the inclusion of a pH800 analyser the Model 762 probe assembly and electrodes become a complete fluoride/RmV sensing unit. The analyser includes all the circuitry necessary for the measurement and transmission of an isolated 4-20mA signal.

The Model 762 assembly is manufactured from chemically resistant polypropylene and has spaces for two PG13.5 electrodes – an industrial fluoride ISE electrode and glass temperature compensator. The reference is a double-junction arrangement with a large gel reservoir giving excellent stability in tough applications.
