FAQs of Sensocon USA Differential Pressure Transmitter Series DPT30-R8 - Range 0 - 508 mmWC:
Q: How is the Sensocon DPT30-R8 Differential Pressure Transmitter installed?
A: The DPT30-R8 is designed for wall mounting and includes mounting screws and an installation manual. Pressure connections are made using barbed fittings for 6 mm I.D. tubing, and the electrical connection uses a 2-wire, 420 mA output for streamlined integration into control systems.
Q: What types of media can the DPT30-R8 measure?
A: This transmitter is suitable for measuring differential pressure in air and non-corrosive gases only. Its silicone seal and ABS plastic housing ensure compatibility and reliable performance in HVAC and cleanroom environments.
Q: When should I use the zero/span adjustment feature?
A: Zero and span adjustments are necessary during initial setup or when recalibrating the transmitter to maintain accuracy over time. The DPT30-R8 allows this adjustment easily through built-in push buttons on the device.
Q: Where can the DPT30-R8 be used effectively?
A: Ideal for industrial applications, the DPT30-R8 is commonly installed in HVAC systems, cleanrooms, laboratory ventilation, and other environments where differential pressure monitoring of air or non-corrosive gases is critical.
Q: What benefits does the LCD digital display offer?
A: The integrated LCD digital display provides real-time, easy-to-read pressure values directly at the installation site, aiding rapid troubleshooting and adjustment during system operation or maintenance.
Q: How does the overpressure limit enhance device longevity?
A: With an overpressure limit of 300% of full scale, the DPT30-R8 is protected against accidental high-pressure spikes, reducing the risk of sensor damage and extending the operational lifespan of the device.
