T-Probe

For retro-fitting to V100 and V110 meters

Most V100 and V110 meters have the probe location hole

in the body and a driving magnet fitted. V100 or V110

meters without this facility cannot be retro-fitted with

a T-probe.

The brass bodied V100 (Kent PSM) and some versions of the

thermoplastic V110, can be specified with the facility for a magnetically

operated (reed switch) pulsed output, by the retrofitting of a dedicated

probe assembly.

The probe is fitted with a 100Ω series resistor to protect the reed switch

from power surges and is usually provided with a 5 metre length of

cable, terminating in a sealed flying lead.

Page 3 Cable Identification and Wiring Details: The factory fitted cable used for the T-Probe is defined as 4 x 7 / 0.2mm with Red, Blue, Black and Yellow as the core colours, contained within a white outer sheath.
Page 4 For ‘TL2’ variant, the RED and BLUE cores are the volt free pair. The loop-back is across the BLACK and YELLOW cores. These connections are not otherwise polarity sensitive. Note: The reed switch assembly is rated at 50 Vdc maximum working. The duty cycle of the switch closure is typically 70% on, 30% off.
