Precision in Low-Range Differential Pressure

Designed for sensitive differential pressure applications, the DPT1-R8 excels at monitoring subtle pressure changes with a full-scale stability of 0.5% per year. The silicone sensor and polycarbonate housing provide longevity and reliability, ensuring accurate data for critical industrial processes. Its electronic processing guarantees consistent performance in dry air and non-aggressive gas environments.

Easy Installation and Configuration

Installation is made straightforward with the included mounting bracket and screw terminal electrical connection. The transmitter's zero and span are adjustable by push button, so on-site calibration is simplified. With no built-in display, the device is intended for integration into control or monitoring systems that accept standard 4-20mA signals.

FAQ's of Sensocon USA Differential Pressure Transmitter Series DPT1-R8 - Range -0.25 - 0.25 mbar:

Q: How do I install the DPT1-R8 differential pressure transmitter?

A: Mount the transmitter on a wall using the supplied mounting bracket. Connect the two 1/8" NPT ports to your process lines and wire the screw terminal block for power (10-30 VDC) and the 4-20mA output signal.

Q: What media can be measured with this differential pressure transmitter?

A: The DPT1-R8 is compatible with dry air and non-aggressive gases, as well as measuring pressure differentials in steam, oil, and gas applications commonly found in industrial settings.

Q: When should I use this transmitter instead of a general-purpose sensor?

A: Choose the DPT1-R8 when precise monitoring of very low pressure differentials, between -0.25 and 0.25 mbar, is required, or when you need high stability (0.5% FS/year) and robust environmental protection (IP65 rating).

Q: What are the benefits of the zero and span push-button adjustment?

A: The push-button zero and span adjustment feature simplifies on-site calibration, saving time and reducing the chance of error compared to manual potentiometers or software-based setups.

Q: Where should the DPT1-R8 be used in a facility?

A: It is best suited for industrial areas where accurate low differential pressure measurement is needed, such as HVAC duct pressure monitoring, cleanroom environments, or process control for non-aggressive media.

Q: What electrical connections are required for operation?

A: The transmitter requires a DC power supply (10-30 VDC) wired to its 2-wire screw terminal block, which also carries the 4-20mA output signal compatible with most industrial monitoring systems.

Q: How does the enclosure rating of IP65 benefit my installation?

A: The IP65 polycarbonate enclosure ensures that the DPT1-R8 is resistant to dust and water jets, providing reliable operation in demanding and potentially wet or dusty industrial environments.
