Details:

Pressure measurement is one of the most important parameters in the operation and control of most industrial processes, allied services and utilities. Not only the pressure measuring instruments must be designed to be inherently accurate and reliable but they must also be periodically calibrated so as to ensure continued reliable and accurate measurements. The digital pressure instruments described below are excellent microprocessor based instruments, which have been designed taking into consideration these criteria.

 Digital Pressure Calibrator Model PSI-PC 1 

Model PSI-PC 1 is a microprocessor based instrument which employs highly stable, temperature compensated pressure sensors and advanced multipoint lineraisation software to provide  excellent accuracy of ± 0.1% FS. With its high stability and reproducibility, Model PSI-PC 1 is an excellent instrument, for calibration of pressure meters and indicators.  It can be specially customized to give accuracy of ± 0.05% FS for more demanding calibration requirements.  Its advanced features include selection of any of the most common 11 pressure units just by press of the Unit key. The selected unit remains stored in the internal non-volatile memory. The other two key functions are Peak Hold & Auto Zero

 For special applications the instrument can be provided with Data Transfer facility to PC. These calibrators are also available without software linearisation for routine measurement of pressure where lower accuracy of ± 0.25% or ± 0.5% of FS is acceptable.

 These instruments are available in two types of cabinet i.e. Handheld and Tabletop. While Tabletop model can accommodate any type of pressure sensor from low to very high, the Handheld model is provided for low pressure ranges i.e. up to 30 PSI.  Calibrators are available for various full scale pressure ranges from as low as 100 mm WC to 10000 PSI. The normally available sensor for differential pressure measurement include 0-0.3 PSI, 0-0.8 PSI, 0-1 PSI, 0-3 PSI,0-5 PSI, 0-15 PSI, 0-30 PSI, 0-100 PSI and 0-150 PSI F.S.  They are suitable for non corrosive media such as air etc. For liquids and corrosive gases pressure sensors with stainless steel isolated diaphragm and SS body are available for any pressure range from 15 PSI to 10000 PSI for gauge pressure measurements in the form of an external sensor probe

 Digital Pressure Indicator & Controller   Model PSI-DPG

 Model PSI-DPG is a mains-operated, microprocessor based pressure indicator and controller, which finds applications in industrial processes where accurate indication of pressure of expensive gases liquid and air is required. It has also features, which enables it for use in On/Off control applications. It is programmable for 1 or 2 independent alarm settings, provides potential free relay contacts for each alarm value with delay times settable from 0 to 50 seconds and factory set hysterisis from 5% to 20%. It has the facility for user-defined averaging of measurements to take care of fluctuations of the same.
