Devices series DTM (DTM-1, DTM-2U), EQ-1U, AKVM-1U are designed to measure gauge pressure in different environments. Devices of this series can work with liquids, steam and gas, provided that the environment in which measurements are made, has no corrosive properties to the materials.
The devices are signaling. When the pressure set-point values, the devices can control external circuits. In this way, devices can signal the attainment of the boundary values of the pressure in the process, enable or disable alarm devices or actuators.
Made from contacts that are triggered when the lower or upper boundary value of the specified parameter.
There are two versions of this series of devices. Option 1 – version for operation in temperate climates, the version "Y", category 3. Option 2 – performance for areas with dry and humid tropical climate, the execution of T, category 3.
The devices have the following measuring ranges (kgf/cm2):
For devices of the series of WC-1 In: 1; 1,6; 2,5; 4; 6; 10; 16; 25; 40; 60; 100.
For EKM-2U: 160; 400; 600; 1000; 1600.
For vacuum gauge EQUIV-1U: from -1 to 0.
For solids ACMV-1U: -1 to 0.6; from -1 to 1.5; -1 to 3; from -1 to 5 -1 to 9; -1 to 15; from -1 to 24.
All the series have the class measurement accuracy -1.5.
The device is connected by means of the connecting fitting with thread M20x1,5.
The error response of the electrical contacts signaling device is ±2.5 percent of the sum of the limits of measurement.
Unit weight is not more than 2.5 kg.
Nominal voltage for appliances is 220V DC or 220V AC at 50Hz.
