Static pressure, dynamic pressure, and total pressure describe three different aspects of the same flowing fluid. Get them confused and a Pitot tube reading turns into the wrong velocity, an HVAC fan is undersized, or a leak test passes when Read More
A PID controller takes the difference between where a process is and where you want it to be (the error), then computes a corrective output using three weighted terms — proportional, integral, and derivative — and feeds that output back Read More
Contents What is a piezoelectric pressure sensor Working principle: stress to voltage Why static pressure cannot be measured Charge mode vs IEPE/ICP signal conditioning Sensor materials: quartz, PZT, PVDF Operating temperature limits and thermal shock Piezoelectric vs piezoresistive: decision matrix Read More
Cryogenic pressure transducer for low temperature pressure measurement. -196℃～+125℃, -260℃/-350℃ (special models). Sino-Inst offers a variety of low pressure transducers for industrial pressure measurement. If you have any questions, please contact our sales engineers. Description The Cryogenic pressure sensor adopts Read More
Updated: April 23, 2026 A pressure gauge gives you a number on a dial. A pressure transmitter sends a 4-20 mA signal to a control system. That single sentence drives 90% of the selection decision. The remaining 10% is where Read More
Updated: April 21, 2026 | Sino-Inst Engineering Team The cheapest way to convert a 4-20 mA loop signal into a voltage for a PLC or recorder analog input is a single precision resistor in parallel with the input. A 500 Read More
Updated April 20, 2026 by Sino-Inst Engineering Team A 4–20 mA pressure transmitter with “no output” looks like a dead sensor, but it almost never is. In our field records, 80% of no-output calls trace to five things: wrong wiring Read More
Updated on April 18, 2026 — Most DP transmitter measurement errors trace back to installation mistakes — not faulty hardware. Incorrect mounting orientation, improperly sloped impulse lines, or a skipped commissioning step can introduce errors that persist for years. This Read More
Updated Apr 17, 2026 — A pressure transmitter is only as accurate as its installation. Get the mounting position wrong, run sloppy impulse lines, or skip the root valve, and you will chase phantom readings for months. This guide walks Read More
Updated: April 10, 2026 A pressure sensor converts mechanical pressure into an electrical signal. It is the sensing element inside every pressure transmitter, transducer, and switch used in industrial process control. The electrical output—typically a change in resistance, capacitance, or Read More
