Signet 8630 Chlorine Transmitter

T

Member of the ProcessPro® Family of Transmitters

Description

The Signet 3-8630-3P ProcessPro
Chlorine Transmitter simultaneously
displays free chlorine and pH levels on a
bright LCD backlight display.

The 8630 transmitter has two 4 to 20
mA outputs that can be programed to
transmit chlorine, pH or temperature
information to a data collection device.

(sold separately)

8630-3P

Two dry-contact mechanical relays can
be used to deliver an alarm signal or
activate a chlorine dosing system.

Programming is simple and easy with
Signet’s standard 4 button keypad.
The menu option allows the use of
an optional pH sensor to accurately
calculate free chlorine level or
select “Manual pH input” and enter
the applications stable pH level to
determine free chlorine levels.
