INSTALLATION
3.1 A
Mechanical installation - Basic GasCheck
The sensor is designed to be mounted directly onto a printed circuit board
(PCB). The sensor should be secured with two M4 screws (M4 x 8 mm pan
head screws with a plain and spring coil washer recommended). Pads should
be provided on the PCB for electrical connection (
1.9 mm pads with
1.0
mm holes recommended) and the pins on the sensor should be soldered
directly to these pads.
In designing the PCB to accept the sensor, consideration should be given to
the inlet and outlet pipes to ensure that these do not collide with tall
components.
