ecoPRESS EX1-01 Differential pressure transmitter The transmitter is used to measure the differential pressure value. Reading the pressure value and configuration of transmitter parameters is done by means of Modbus RTU protocol, in RS485 standard. Modbus registers include, among others, information on the currently set measuring range, time constant, percentage value of pressure difference related to the range and signaling of exceedances of the sensor’s measuring range. The transmitter enables reading the value of differential pressure with the use of voltage analogue output [0-10 VDC]. The transmitter cooperates with the ventilation system controllers and any industrial automation. Functions • • • • • • • • • • • • • • Built-in differential pressure sensor. Controlling of constant flow and detection of the degree of filter contamination. Converting differential pressure to flow. Analogue voltage output 0-10 VDC to read the value of voltage proportional to the measured pressure. Possibility of setting one of eight available ranges of voltage output 0-10 VDC. The LED indication of the operating status of the transmitter. Zero point calibration. Communication in the RS485 standard with any industrial automation. Wide range of transmitter power supply voltage. Cooperation with ventilation system controllers and configuration of transmitter parameters from the controller service menu. Supplying the transmitter from an external power supply or directly from the controller socket. Possibility of setting the time constant of measurement. Optional reading of values and configuration of transmitter parameters using Modbus RTU protocol. Installation on flat surface.
