The high precision pressure transducers model 8201, type H are of a sturdy and compact construction. Due to their resistance against mechanical strain they enable exact measurements.
Therefore they can not only be used in laboratories of research and development but are also very suitable for process quality control in the industrial sector. The material and the resistance strain gauges are the guarantees of a long-term stability and a high degree of reliability for the user. As the high precision pressure transducer is resistant against aggressive media being either liquid or gaseous, the measurements are easy to handle.

The construction of the transducer is realized without moving parts so that it is highly insensitive against shock loads and vibrations.
For critical cases of application a set of PTFE rings is available to seal the pressure port.

Customized models are available on request.

Description

The high precision pressure transducers can be configured with a lot of options, the standard version is available ex stock.
The medium is led via the pressure port into the measuring chamber, which is closed with a welded diaphragm, the measuring element. The diaphragm is deformed in proportion to pressure exercised. On the reverse side of the diaphragm a 4 arm strain-gauge bridge is applied. The physical value pressure is converted into an electrical change of resistance.
The measuring of pressure is performed against ambient pressure, the space behind the diaphragm is in connection with the reference atmosphere.

Each transducer is available with an internal amplifier, a so-called pressure transmitter with a voltage or a current output.
The electric connection is made by plug or integral cable. The pressure port is formed by a M 16 x 1.5 metric female thread with sealing ring slot. With the help of adaptors, part of our product range, the pressure port can be changed.
