TRANSMITTERS FOR LOW PRESSURE
The APR-2000ALW/G transmitter is applicable to the measurement of differential pressure of gases. Typical applications include the measurement of blast pressure, chimney draughts or pressure / under pressure in furnace chambers. The ability to select the radical conversion characteristics enables the transmitter to be used in gas-flow measurement systems using reducing pipes or other impeding elements.The transmitter can withstand over pressure up to 1 bar. The housing of the electronic circuit has the degree of protection IP66/IP67.
4…20 mA output signal + HART protocol
Display with backlight
Programmable range, zero shift, damping ratio and characteristic with local panel keys
Selectable linear or radical conversion characteristic
Accuracy from 0,1%
Intrinsic safety certificate (ATEX, IECEx)
Safety version SIL2/SIL3

ELECTRO-PNEUMATIC INTERSYSTEM TRANSMITTER type A201 IS USED FOR CONVERSION THE STANDARD ANALOGUE ELECTRIC SIGNAL ON STANDARD PNEUMATIC SIGANL AT RANGE 20…kPa OR 60..300kPa IN AUTOMATIC REGULATION SYSTEMS OR CONTROL INDUSTRYSYSTEMS. THIS TRANSMITTER POSSESES COOPERATION THE ELECTRONIC AUTOMATION SYSTEMS WITH EXECUTIVE ELEMENTS. THE TRANSMITTER’S WORKING IS BASED ON COMPARISON MOMENT RULE OF FORCE MADE BY COIL WHICH WAS PUT IN
CONSTANT MAGNETIC FIELD PROPORTIONAL FOR INPUT SIGNAL, WITH MOMENT OF FORCE MADE BY METALIC PRESSURE CAPSULE OF FEEDBACK, WHERE THE PNEUMATIC OUTPUT SIGNALIS SUPPLIED. CHANGE OF DIRECT OF TRANSMITTER WORKING (”DIRECTLY” OR “INVERSELY” WORKING) MIGHT BE REALIZED BY CHANGE CURRENT FLOW DIRECTION BY COIL AND CORRECTION OF TRANSMITTER REGULATION.
Input: 4..20 mA; 0..20 mA
Output: 0,2..1bar; 0,6..3bar
