A L M India deals in products related to Measure and control of differential pressure, flow, temperature and relative humidity.A L M? is basically into instruments related to measure and control of differential pressure, flow, temperature, relative humidity and level.These instruments are manufactured as well as imported and exported from various countries. A L M distribute and sell for TIWAC Division [A Division of Walchandnagar Industries Ltd., India],Dwyer Instruments, Inc., USA, Novasina, Switzerland,E+E Elektronik, Austria,Huba Control, Switzerland,Gray Wolf Sensing Solutions, USA,Kimo Constructeur, France.

High precision measurement instrument for monitoring of differential pressures, available in 2 versions as PascalSwitch 20 and PascalSwitch 100.

Outstanding accuracy, reproducibility and long-term stability

Two threshold values including delay function and hysteresis are freely programmable throughout the whole measurement range

Two integrated relays and LED`s indicate when the threshold values are crossed

The sensor is easy to calibrate by the end user

The device parameters can be set easily by using the PascalTool-Palm configuration software or a Palm PC emulator

Option:Special version PascalSwitchC 20 and PascalSwitchC 100 with RS232-connecting interface for an easy integration in a process visualisation or control system. A DLL [Dynamic Link Library] as software development kit is also available.
