Designed to convert excess pressure (PI), absolute (DA), vacuum (DV), excess pressure and vacuum (DIV), pressure difference (DP) of air, natural and neutral gases, water, oil into a standard current signal (4-20 )mA and display the current value on the digital display. The sensors have versions: general industrial and explosion-proof. Pressure sensors of the Ex version can be used in explosive conditions, have the type of explosion protection “ia” - an intrinsically safe electrical circuit and the explosion protection marking “0Exia IIAT5 X”. The sensors can be used to operate in systems for automatic monitoring, regulation and control of technological processes in various industries, including in explosive industries (for Ex type sensors), in heat power engineering, in the gas industry, ventilation systems and other industries. Types of models DDM-03-MI: DDM-03-MI - 3-limit with an indicator for general industrial design; DDM-03-MI-Ex – 3-limit with an explosion-proof indicator marked “0Exia IIAT5 X”. Features 3 customized ranges; Output signal (4-20) mA; Working pressure for DD up to 25 kgf/cm; Explosion-proof version of the device; Intervalidation interval is 2 years; Working medium: gas, air, liquid
