The probes are fitted with 10 metres of cable as standard.
For longer cable lengths (up to 25 meters) use a junction box (08350=A=8500) and the 2654 cable
(358048,00000).
For cable lengths greater than 25 meters, use a pre-amplifier unit (08350=A=8000) and the
2666 cable (370=506=025). In this case it will not be possible to monitor the impedance.
Connection to the 9135 transmitter
Directly to the 9135
1 pH module 5 Input (measured pH or redox) - transparent
2 Probe 6 Ref. (reference) - black
3 Temp+ (PT100) - white 7 Liquid earth (liquid contact) - blue
4 Temp- (PT100) - red 8 External shielding - EMC protection
Using the pre-amplifier unit
With this scenario it is impossible to connect the solution ground.
