1 Intended use
The pressure sensors are designed for the connection to an hand-held instrument of the following types:
GMSD 3111, GMSD 3151 and GMSD 3156 as well as GMSD 3110, GMSD 3150 and GMSD 3155
And to the universally pressure measurement system:
GDUSB 1000
The sensors in plastic housing are designed for following application areas:
•air
•non-corrosive, non-ionising gases
Tube connection:
Be careful when mounting tubes to the pressure ports!
Only press tubes on port in straight direction –avoid side forces to the ports, because these may break the port.
Only use plastic tubes with inner diameter of 4 mm, e.g. 6/4 (Ø 6 mm outside / Ø 4 mm inside).
2 General
Read through this document attentively and make yourself familiar to the of the device before you use it.
Keep this document in a ready-to-hand way in order to be able to look up in the case of doubt.
3 Disposal
This device must not be disposed as “residual waste”.

4 Operating and Maintenance Advice
a.) You must only use the sensor with GMH 3111, GMH 3151, GMH 3156 or GDUSB 1000 devices!
Usage of other devices may result in destruction of sensor and device.
b) Treat sensor and device carefully. Use only in accordance with above specification. (do not throw, hit against etc.).
Protect plug from soiling.
c) To disconnect pressure sensor do not pull at the cable but at the plug (to open lock).
When connecting the sensor make sure that arrows are pointing upwards and that plug is entered into device
socket centrally. Do not twist plug when entering socket.
If plug is entered correctly, it will slide in smoothly
If plug is twisted or entered incorrectly the connecting pins of the plug can be spoilt by bending or broken
=> Plug can no longer be used and connecting cable needs to be replaced.
d) GMSD … .. - K31 (= standard (plastic) pressure sensors):
Connection diagram for sensor tube connection:
For measurements of over pressure (relative pressure sensor):
•Connect plastic tube with internal dia of 4 mm to cable gland "B".
Connection "A" will not be used!
For measurements of pressure differences (relative pressure sensor):
•Connect both plastic tubes with an internal dia of 4 mm to cable gland "B" and "A";
make sure to apply higher pressure to connection "B"
For measurements of absolute pressure (absolute pressure sensor):
•Connect plastic tube with an internal dia of 4 mm to cable gland "A".
(Cable gland "B" is not used.)
5 Safety requirements:
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and
special safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any
other climatic conditions than those stated under "Specification".
2. If the device is transported from a cold to a warm environment condensation may result in a failure of the device.
In such a case make sure the device temperature has adjusted to the ambient temperature before trying a new
start-up.
3. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be
marked accordingly to avoid re-starting.
Operator safety may be at risk if:
- there is visible damage to the device.
- the device is not working as specified.
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
4. Warning: Do not use this product as safety or emergency stop device or in any other application where failure of
the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.
5. Any changes or repair of the device is not allowed.
Please return device to manufacturer for repair or maintenance.
