Tel-Tru Pressure Transmitters
Accurate, Robust, and Built to Last!
Tel-Tru Pressure Transmitters are offered in a compact all welded
stainless steel housing with a variety of available connections
for the pressure port and electrical connections for output signal
transmission.
The type of pressure transducer or sensor used is appropriate to
the application and accuracy requirement. Electronics within the
housing amplifies and conditions the changing transducer signal
to an industry standard output signal, which is transmitted to a
receiver device such as a readout, recorder, data logger or controller.
|
Things to consider
when selecting
a Pressure Transmitter:
- Output required?
- Accuracy required?
- Pressure range needed?
- Process connection required relative to media being measured?
- Electrical connection for interface with plant system?
