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
Updated: April 10, 2026 Class 1 Div 1 and Class 1 Div 2 are two NEC hazardous location classifications that define how likely flammable gases or vapors are to be present. The distinction matters because it determines what type of Read More
Updated Apr 9, 2026 — Reviewed by Sino-Inst Engineering Team In fluid mechanics, pressure splits into three components: static pressure, dynamic pressure, and total pressure. These are not three separate forces — they are three ways of describing the energy Read More
Updated April 2026 — By Sino-Inst Engineering Team A pressure transmitter converts the mechanical force of fluid or gas pressure into an electrical signal — typically 4–20 mA or a digital protocol like HART. That signal goes to a PLC, Read More
Updated April 2026 — By Sino-Inst Engineering Team Wiring a pressure transducer correctly is the difference between a clean 4–20 mA signal and hours of troubleshooting. The three wiring configurations — 2-wire, 3-wire, and 4-wire — each have different power Read More
