TPDL Differential pressure transmitter for liquids and gases

Description

The transmitter consists of a sensor housing of
stainless steel and a ceramic membrane. Resistors
in thick film technology are applied to the membrane.
As pressure affects the membrane, it results in a
change of resistance depending on the bending of
the membrane, and this is then converted into a
proportional output signal by means of the built-in
electronics.
The construction, incorporating only one moving part
and a direct signal from the membrane, offers a high
level of accuracy and a short response time. The
properties of the membrane also ensure good stability
is maintained over time, as well as a low temperature
dependency.

Tecnical description

Transmitter for measuring differential pressure in liquids and gases. The method of measurement using a ceramic membrane gives a high level of accuracy and stability over a long period.

• Several measuring ranges up to 2500 kPa (25 bar)
• Can withstand overpressure of up to 6 times the measuring range (depending on model)
• Accuracy <1.25% of measuring range
• Output signal 0…10 V DC or 4…20 mA
• Highly durable in most environments
• Excellent long-term stability and low temperature dependency
