5.1.2 Requirements for mounting point

The mounting point must meet the following conditions:
Environment corresponds to a max. pollution degree of 3.
■
Humidity ≤ 80 % r. h. (non-condensing).
■
Protected from weather influences.
■
EN
Sealing faces are clean and undamaged.
■
Sufficient space for a safe electrical installation.
■
For information on tapped holes and welding sockets, see technical information
■
IN 00.14 at www.wika.com.
Permissible ambient and medium temperatures remain within the performance limits.
■
Consider possible restrictions on the ambient temperature range caused by mating
connector used.
For performance limits, see chapter 11 "Specifications".
■

5.1.3 Mechanical mounting

The max. torque depends on the mounting point (e.g. material and shape). If
you have any questions, please contact our application consultant.
For contact details, see chapter 1 "General information" or the back page of
the operating instructions.
1. Seal the sealing faces.
2. At the mounting point, screw the pressure transmitter in hand-tight.
⇒
When screwing in, do not cross the threads.
3. Tighten with a torque wrench using the spanner flats. The maximum torque of the
CPT2500 is 50 Nm; for flush connections, 40 Nm.

5.2 Electrical connection with USB adapter CPA2500

Only model CPT2500 pressure transmitters can be used in connection with
the CPA2500 USB adapter! Using other sensors could damage both the
adapter and the sensor.
Connecting the sensors
1. Change the sensor in the depressurised state.
2. Connect the 7-pin connector to the USB pressure sensor in accordance with the
orientation guide and secure it through the connection sleeve. Turn the connection
sleeve clockwise without much force.
When connecting, the connector might not locate properly in the socket. In this
event you should try holding the connector by the bend protection, rather than by the
connector sleeve.
