Application and Construction
Smart pressure transmitters are applicable to the measurement of the pressure, underpressure and absolute of gases, vapours and liquids. The active sensing element is a piezoresistant silicon sensor separated from the medium by a diaphragm and by specially selected type of manometric liquid. The casing is made of aluminum alloy cast or 316SS stainless steel, degree of protection IP66/IP67. The design of the casing enables the use of a local display, rotation of the display, rotation of the casing by 0-340° relative to the sensor, and a choice of cable direction.
The communication standard for data interchange with the transmitter is the Hartprotocol.
Communication with the transmitter is carried out with:
- a KAP-03, KAP-03Ex communicator
- some other Hart type communicators, (*)
- a PC using an HART/USB converter and Report 2 configuration software.
The data interchange with the transmitter enables users to:
- identify the transmitter
- configure the output parameters:
- measurement units and the values of the start points and end points at the measurements range
- damping time constant
- conversion characteristic (inversion, user’s non-linear characteristic)
- read the currently measured pressure value of the output current and the percentage output control level
- force an output current with a set value
- calibrate the transmitter in relation to a model pressure
Installation
The transmitter can be installed directly on the installation. An universal mounting bracket is provided to transmitter fitting on 2″ pipe. 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 Micromod diaphragm seal. Installing accessories and a full scope of diaphragm seals are described in detail in the further part of the catalogue. The transmitter’s electrical connections should be performed with twisted cable. The place for the communicator should be assigned before the communicator installation.

SMART PRESSURE TRANSMITTER APC-2000ALW version with MID
Application
Smart pressure transmitter APC-2000ALW MID is applicable to the measurement of the pressure and absolute pressure in application designed according to directive 2004/22/EC (MID), harmonized standard PN-EN12405-1:2005 + A2:2010 and recommendation OIML R140:2007. Device subcomponent suitable for custody transfer measurement of gas with MID approval. Mechanical construction and installation of the transmitter enclosure shall comply with the transmitter APC-2000ALW are described on the catalogue. Pressure transmitters APC-2000ALW MID are produced only with nominal ranges according to the table. Transmitter due to factory blockade of transmitter’s configuration cannot be configurable by user. Available are only terminals SIGNALS + and SIGNAL -. Note! For custody transfer applications, the cover clamp screws have to be locked with seal wire.
