Application and construction
The PCE-28 pressure transmitter is applicable to the measurement of the pressure, under pressure and absolute pressure of gases, vapors and liquids. The active sensing element is a piezo resistant silicon sensor separated from the medium by a diaphragm and by specially selected type of manometric liquid. The electronics is placed in a casing with a degree of protection from IP 65 to IP 68, depending on the type of electrical connection applied.
Calibration
Potentiometers can be used to shift the zero position and the range by up to ±10%, without altering the settings.
Installation
The transmitter is not heavy, so it can be installed directly on the installation. When the pressure of steam or other hot media is measured, a siphon or impulse line should be used. The needle valve placed upstream the transmitter simplifies installation process and enables the zero point adjustment or the transmitter replacement.
When the special process connections are required for the measurement of levels and pressures (e.g. at food and chemical industries), the transmitter is provided with an Aplisens diaphragm seal. Installing accessories and a full scope of diaphragm seals are described in detail in the further part of the catalogue.
Measurements under explosion hazard
ATEX Intrinsic safety version is available for taking measurements in zones under explosion hazard. The installation of the transmitter in a zone under explosion hazard requires the use of a Ex power supply. We recommend the use of the Aplisens ZS-30Ex1, ZS-31Ex1 power supply and separator.
