V Automat & Instruments Pvt. Ltd. Manufactures Microprocessor based Differential Pressure Flow Transmitters. V Automat & Instruments Pvt. Ltd. Is ISO 9001 certified company. Microprocessor based Differential Pressure Flow Transmitters can also be used to measure level and pressure. 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 is maximum 0.004 inch [0.10mm] and 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.
V Automat & Instruments Pvt. Ltd adopts the principle of replacing analog signal amplifying circuit and A/D conversion circuit with direct digital capacitive circuit, and meantime takes the digital compensation technology to compensate temperature and static pressure, which greatly improves the measurement precision and reduces the temperature drift. The complete unit of the transmitter is characterized by its small size, high reliability and long-term stability. With extremely high performance price ratio this Microprocessor based Differential Pressure Flow Transmitters is maintenance free & accurate. The circuit within the transmitter provides Reverse polarity protection, Transient power surge protection, and Electromagnetic interference [EMI] protection.
