OEM Silicon Pressure Transducers

-- Steady & Reliable Manufacturer --

Product Overview

Our OEM Silicon Pressure Transducers are the compact, core sensing elements preferred by manufacturers building systems where space, reliability, and cost are critical factors. Utilizing advanced piezoresistive silicon technology, these transducers convert pressure directly into a stable electrical signal (voltage or current), making them perfect for integration into control valves, HVAC equipment, small pump controllers, and appliance pressure sensing. They are optimized for high-volume, low-cost manufacturing without sacrificing quality or long-term stability.

Key Features

Piezoresistive silicon chip technology for stability.
Miniature, compact design for easy OEM integration.
Optimized pricing for high-volume blanket orders.

Payment and Shipping Details

We specialize in long-term OEM contracts with negotiated payment terms such as Net 30/60 days following credit approval, in addition to standard T/T upfront. Our preferred shipping terms are EXW (Ex Works) or FCA (Free Carrier). Standard units have very short lead times (5-7 days) due to automated production lines. Custom configurations require 15-20 days for tooling and testing.

Frequently Asked Questions

Q: What does 'Ratiometric Output' mean?
A: A ratiometric output signal scales its voltage proportionally to the supply voltage. This helps eliminate reading errors caused by minor fluctuations in the power supply to the transducer.

Q: Is the ceramic diaphragm better than stainless steel?
A: Ceramic diaphragms (often used in lower pressure ranges) offer excellent chemical compatibility and higher corrosion resistance than 316L SS in many media, but they may have lower burst pressure ratings.

Q: Are these transducers temperature compensated?
A: Yes, all our silicon transducers feature active temperature compensation across the specified operating range to ensure accuracy is maintained through temperature variations.
