Vacuum Pressure Transmitters

Vacuum Pressure Transmitters

Vacuum pressure transmitters are precision instruments used for monitoring and measuring vacuum pressures. The unit is factory calibrated to deliver an output of 4 mA at 0 pressure and 20 mA at full scale but can be field calibrated as needed. The pressure range for this transmitter is from -1 bar vacuum to 0 bar, with accuracy better than 0.25% FS, and the transducer is rated at 50 million cycles. The transmitter is made of Type 316 stainless steel and is temperature compensated by means of laser-trimmed resistors. It is protected against reverse voltage, overvoltage, and noise on the supply line, and has a wide supply range of 8 to 36V DC, allowing for a wide range of load resistance. This vacuum pressure transmitter has various industrial applications, including monitoring vacuum systems in the semiconductor, food processing, and medical industries.

Application features:

• Monitoring of hydraulic pit props to indicate condition of the prop and ground strata in mining industries
• Monitoring of hydraulic pressure on cutting machinery using hydraulic systems in mining industries
• Monitoring ballast tanks levels and hydraulic pressure on jack-up drilling rigs in oil rigs
• Monitoring pressure on platform flowlines, additive metering pumps, and sub-sea injection valves/well cleanouts in oil rigs
• Monitoring compressor pressure of both low and high-pressure sides in refrigeration
• Control and automatic start-up of modern industrial gas turbines in heavy-duty applications
• Monitoring of steam pressures and distribution pressures within the generating of steam in the electrical industry
• Local and telemetry monitoring of the coolant pressures on oil and nitrogen gas cooled systems used on high voltage three-phase cables in the electrical industry
