Mounting

2 Mounting

2.1 Mounting instructions

The pressure transmitter can be mounted in

any position. Cable entries must point down-

wards to avoid moisture ingress. For this

purpose, the housing can be rotated by 330°

in relation to the mounting part.

An appropriate connection seal must be

used for mounting. This seal is either sup-

plied with the pressure transmitter or must be

provided by the customer.

2.2 Compensation of the atmos-

pheric pressure

On instruments for gauge pressure meas-

urement, the atmospheric pressure is com-

pensated via a breather facility integrated in

the housing.

Pressure transmitter with direct cable

outlet

- via the capillaries of a special cable con-

nected to the terminals, protection IP 68

We recommend leading the special cable into

the external connection housing VEGABOX

01 (accessory) and carrying out the pres-

sure compensation via the integrated

breather facility there.

External connection housing

Observe the following instructions:

- as a rule, there must be the same atmos-

pheric pressure on the breather facility as

on the vessel

- the pressure compensation must be done

in a dry environment

- with vertical wall mounting, cable entries

must point downward to avoid moisture

ingress and buildup on the breather facility.
