WARNINGS

 

AND

 

OPERATING

 

INSTRUCTIONS 

1.

 

Do not expose the probes to gases or liquids that could corrode the material of the sensor or the 
probe itself. Clean the probe carefully after each measurement. 

The pressure sensor is suitable 

for measurement of only non corrosive dry gases or air and not liquid:

 check the membrane 

compatibility with the plant fluid. 

2.

 

Do not bend the probe connectors or force them upward or downward. Do not bend or force the 
contacts when inserting the probe connector into the instrument. 

3.

 

Do not bend, deform or drop the probes, as this could cause irreparable damage. 

4.

 

Always select the most suitable probe for your application. 

5.

 

Comply with the correct polarity of the probes. 

6.

 

In general, do not use temperature probes in presence of corrosive gases or liquids; the probe 
external containers are made of AISI 316 or INCONEL stainless steel, while the contact probe 
containers are made of AISI 316 or INCONEL stainless steel plus silver. Avoid contact between 
the probe surface and any sticky surface or substance that could corrode or damage it. 

7.

 

To obtain reliable measurements, temperature variations that are too rapid must be avoided. 

8.

 

Temperature probes for surface measurements (contact probes) must be held perpendicular 
against the surface. Apply oil or heat-conductive paste between the surface and the probe in 
order to improve contact and reduce reading time. Whatever you do, do not use water or solvent 
for this purpose. A contact measurement is always very hard to perform. It has high levels of 
uncertainty and depends on the ability of the operator. 

9.

 

Temperature measurements on non-metal surfaces usually require a great deal of time due to the 
low heat conductivity of non-metal materials.  

10.

 

Probes are not insulated from their external casing

; be very careful not to come into contact 

with live parts (above 48V). This could be extremely dangerous for the instrument as 
well as for the operator, who could be electrocuted. 

11.

 

Avoid taking measurements in presence of high frequency sources, microwave ovens or large 
magnetic fields; results may not be very reliable. 

12.

 

Clean the probe carefully after use. Clean the sensor pressure chamber carefully. Avoid deposits 
or incrustations left by the fluid coming into contact with the membrane, as with time this could 
cause measurement errors.  

13.

 

Avoid inserting nails or spikes into the pressure chamber as the membrane could be 
unintentionally torn.  

14.

 

In order to fix the probes, use a suitable fixed wrench, and possibly sealing gaskets.  

15.

 

The instrument is water resistant and IP66, but is not watertight and therefore should not be 
immersed in water without closing the free connectors using caps. The probe connectors must 
be fitted with sealing gaskets. Should the instrument fall into the water, check for any water 
infiltration. Gently handle the instrument in such a way as to prevent any water infiltration from 
the quick couplings' side.
