V. Automat & Instruments (P) Ltd is one of the prime Manufacturers, Exporters and Suppliers of Differential Pressure Transmitter of 501 Series in India. 501 Series Automat Differential Pressure Transmitter is the part of series 501, consisting of certified electronic. 501 series SMART DP/PT are microprocessor-based instruments that combine the analog signal advantages (4-20 mA) together with the flexibility of digital communication using HARTÂ® protcol/Foundation Field Bus (FF). The DP/DT can be configured by using universal Hand Held HART communicator (HHT) or by Computer (PC) with dedicated Automat Software.
The medium pressure is transferred to the measuring chaff in the center of the chamber. The medium pressure is transferred to the measuring chaff which is elastic element used to check and measure the pressure acted on it. The displacement of the measuring chaffs [Max. 0.004 inch (0.10m)] is in direct proportion to the differential pressure. The position of the measuring chaff is detected by the fixed capacitive plates at two sides by means of direct digital capacitive circuit.
The electronic signal is ambient, temperature compensated and amplified by the differential amplifier. The signal pass filter dampens the effects of process turbulence and prevents saturation of the DC amplifier and the current driver. The DC amplifier provides non interacting Zero and Span adjustments.
Differential Pressure Transmitter adopt the principle of replacing analog signal amplifying circuit and A/D conversion circuit with direct digital capacitive circuit, and meantime take the digital compensation technology to compensate temperature and static pressure, which greatly improves the measurement precision and reduces the temperature drift. The complete unit transmitter is characterized by its small size, high reliability and long-term stability. With extremely high performance this microprocessor based digital smart transmitter is maintenance free & accurate. The circuit within the transmitter provides Reverse polarity protection, transient power surge protection, and Electromagnetic interference protection. Apart form flow measurement; DP transmitter can also be used to measure level and pressure.
