Data Loggers | LM-P Pressure

LM-P-PRO Series Differential Pressure Indicator / Data logger

The LM-P-PRO series of differential pressure data logger / indicator is very helpful in monitoring differential pressure especially for clean rooms. Large 0.56” LED digital display eliminates the human error in reading the data. The device is field programmable (configurable) for most common of the eight measuring units. The decimal point gets selected automatically for displaying with best resolution.

It also has a feature to set the high and low alarm limit. Whenever the limit is crossed, appropriate LED indicates the alarm condition. Display also starts blinking, for better attention.

Programming of various parameters like, unit, alarm limits, calibration parameters (zero and span), communication parameters etc. are all settable through 4 keys. Data is scanned every second. It has RS485 2/4 wire communication port to connect to any SCADA using MODBUS RTU/ASCII protocol. User can get the current data and device identification information over protocol.

Device also has an optional memory to store the data. It is possible to store the data at an interval between 1 second to 18 hours interval . The stored data can only be retrieved through our web- based data acquisition software gtekNet^TM. It is also possible to configure the entire device from this software. gtekNet^TM enables the user to see, modify, generate report with 21CFRPart 11 compliance using any standard browser from anywhere over network connected device.
