Import Differential Pressure Transmitter — Buy in Bulk from Supplier in China

The R&B Instruments Inc. differential pressure transmitter measures pressure differences between two points using a differential capacitance sensing principle. It operates across a measurable range of 0 to 100 kPa, with an accuracy of ±0.25% FS and a resolution of 0.01 kPa, as stated in the product data. The housing is constructed from 316L stainless steel with an O-ring seal rated for IP65 ingress protection, ensuring resilience in humid or dusty industrial settings.

This device is designed for continuous operation in environments with temperatures ranging from -20°C to 80°C and can withstand static pressures up to 4 MPa. The sensor element is calibrated using NIST-traceable standards, and the output signal is configurable to 4-20 mA or 0-10 V DC, aligning with common industrial control systems. While the listing does not specify exact certifications, the use of 316L stainless steel and IP65 rating are standard for transmitters in chemical and water treatment applications.

Primary buyers include process engineers in oil and gas facilities, pharmaceutical manufacturers, and HVAC system integrators who require reliable pressure differentials for flow control and filtration monitoring. The product is typically shipped in anti-static foam packaging within corrugated cardboard boxes, with bulk orders accepted. Trade terms include FOB Shanghai and payment via T/T, though MOQ and lead time must be confirmed directly with the supplier.

R&B Instruments Inc. is listed as an imported supplier based in Shanghai, with a physical address in Building 32-7B, No.288 Xinzhuan Road. The company's profile does not disclose years in business, employee count, or revenue figures. Its trust tier is classified as 'harbor', indicating basic verification through shipping documentation rather than factory audit. The response rate is recorded as 0.00%, and average response time is not available, suggesting limited buyer communication capacity.

The supplier does not claim certifications, awards, or client references. The product listing attributes technical specifications directly to the device, not to internal testing labs or R&D teams. No evidence of export history, previous buyers, or ISO compliance is provided. Buyers should treat this as a manufacturer of industrial sensors without verified quality management systems unless confirmed directly.
