FAQs of Sensocon USA Differential Pressure Transmitter Series DPT30-R8 - Range -10.0 - 10.0 inWC:
Q: How do I install the Sensocon Series DPT30-R8 Differential Pressure Transmitter?
A: The DPT30-R8 is surface-mounted to a wall or panel using the provided mounting screws. Connect pressure lines to the barbed or 1/8 NPT ports and wire the transmitter using screw terminals found inside the housing. Refer to the included instruction manual for detailed setup steps.
Q: What applications is the DPT30-R8 suitable for?
A: This model is ideal for HVAC systems, clean room pressure monitoring, filter performance tracking, and air flow measurement, specifically for air and non-corrosive gases in industrial and commercial environments.
Q: When should zero/span adjustment be performed on the transmitter?
A: Zero and span adjustments should be done during initial installation, after maintenance, or when recalibrating to ensure measurement accuracy. The push-button digital adjustment feature makes recalibration quick and straightforward.
Q: Where should the pressure transmitter be mounted for best performance?
A: Mount the transmitter on a vertical wall or solid surface near the pressure tap points, away from sources of vibration, excessive moisture, and strong electromagnetic fields to optimize accuracy and longevity.
Q: What is the benefit of the 4-20 mA output signal?
A: A 4-20 mA output is widely compatible with industrial control systems, is less susceptible to signal loss over long wiring runs, and simplifies integration with PLCs or data loggers for remote pressure monitoring.
Q: How does the DPT30-R8 handle overpressure situations?
A: The transmitter is designed to withstand up to three times its rated pressure (maximum 30 inWC), providing robust protection against unexpected pressure surges within typical HVAC and clean room setups.
Q: What materials are used in the construction of this transmitter?
A: The DPT30-R8 features a molded ABS plastic housing in gray finish for durability, and silicone is used for leak-proof sealing, ensuring reliable operation in industrial environments.
