SENSOLUTION™ Model 762 Fluoride
Fluoride Probe Assembly
Order Codes
Full assembly: 500/0060
pH800 Analyser: 500/0080
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.
