Updated May 27, 2026 | Sino-Inst Engineering Team For pressure transducer wetted parts, the choice between 316L and 17-4PH stainless steel is the single most important spec you put on the RFQ. 316L is the default for clean liquid, hydrogen, Read More
Updated May 27, 2026 | Sino-Inst Engineering Team Hydrostatic pressure is the pressure a liquid exerts on a point below its surface, equal to density × gravity × depth. In SI units, P = ρgh — and that single equation Read More
Updated May 26, 2026 | Sino-Inst Engineering Team A submersible pressure transducer measures the hydrostatic head of liquid above its diaphragm and reports it as a 4–20 mA, 0–5 V, or RS485 signal. Choosing one is not “pick the cheapest Read More
Updated May 26, 2026 | Sino-Inst Engineering Team Most pressure transmitter troubleshooting calls trace to one of five things. A 4–20 mA transmitter with “no output” looks like a dead sensor, but it almost never is. In our field records, Read More
Static, dynamic, and total pressure are three flavours of the same scalar — but they appear at different ports of a Pitot-static probe, drive different process instruments, and trip up new HVAC and fluid-mechanics engineers because the textbook prose hides Read More
A 4-20 mA current loop carries a sensor signal across hundreds of meters with near-zero drift. A 0-10 V PLC card cannot accept that current directly. Converting between the two is a five-cent fix on the bench (one resistor) or Read More
Updated May 21, 2026 — A pressure transmitter is only as accurate as its installation. Mount it on the wrong elevation, route impulse tubing without a proper slope, or skip the root valve and you will chase phantom readings for Read More
A pressure transmitter drifts. Diaphragm fatigue, temperature swings, vibration, and process buildup move the zero and span over time. A 0.1 % drift on a 0–1.6 MPa range puts the loop 1.6 kPa off — enough to trip a safety interlock or skew Read More
Pressure is force per unit area, but the unit you put on a gauge depends on the industry, the country, and the instrument. A process plant in Asia reads MPa, an HVAC tech reads inches of water column, a hydraulic Read More
The wetted parts of a pressure sensor are the surfaces that the process media actually touches — diaphragm, port, fill fluid (if any), and any seals or gaskets exposed to the line. Pick the wrong wetted material and the sensor Read More
