SensoGate WA131MH
7
The availability of safeguards is in part dependent on the version of SensoGate WA131MH.
Environmental influences may affect the functionality of safeguards (e.g. components stuck together
by process medium).
1.4 Residual Risks
The product has been developed and manufactured in accordance with generally accepted safety
rules and regulations. However, it is not possible to rule out all risks.
1.4.1 Environmental Influences
The effects of moisture, ambient temperature, chemicals, and corrosion can negatively impact the safe
operation of the product. Please observe the following instructions:
• Only operate SensoGate WA131MH in compliance with the stated operating conditions.
• If possible, install the product inside a protected area of the plant. Alternatively, take appropriate
measures to protect the SensoGate WA131MH (e.g. install ZU0759 protective cap
1)
).
• If using aggressive chemical process media, adjust the inspection and maintenance intervals
accordingly.
• Adhering and sticky process media can impact the functionality of SensoGate WA131MH (e.g., by
causing components to stick together). Adjust the inspection and maintenance intervals accord-
ingly.
1.4.2 Accidental Loosening of the Process Connection
The coupling nut of the screw joint on process connections with a thread may become loose by acci-
dent. This may be caused by manual rotation of the rotating collar when moving to the limit positions
or by process-related vibrations.
Pressurized process medium may escape. Use of an appropriate retainer clamp or locking clamp is
strongly recommended.
Operating SensoGate WA131MH without a retainer or locking clamp is at the risk of the operating
company. The operating company must take action to rule out the possibility of the screw joint cou-
pling nut accidentally loosening.
1.5 Safety Accessories
Specially developed accessories are available to increase safety.
ZU0818 Retainer Clamp for Ingold Socket, 25 mm
The retainer clamp prevents the coupling nut of the Ingold socket (25 mm) screw
joint from accidentally loosening.
The wires of the retainer clamp connect SensoGate WA131MH to the customer’s
process port. A locking lug on the retainer clamp engages in the groove of the
coupling nut (form-fit).

The ZU0759 protective cap protects against the effects of weather exposure and prevents the ingress of external
liquids or particles into the area of the sensor connections.
