Both RTDs and thermocouples turn temperature into an electrical signal, but they fail and shine in opposite places — so the real question is never “which is better”, it is “which fits this point”. This is a selection guide: pick Read More
Updated 2026-06-01 by the Sino-Inst Engineering Team A temperature sensor transmitter is worth fitting only when distance or electrical noise would wreck a raw sensor signal. Run a bare Pt100 a few metres to a nearby panel and you rarely Read More
Updated May 30, 2026 A furnace thermocouple problem is almost always one of three things: the sensor itself, the compensating cable or its polarity, or the cold junction. You can pin down which one in under 20 minutes with a 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
An RTD (resistance temperature detector) measures temperature by tracking how the resistance of a platinum element rises with temperature. A thermocouple measures temperature by reading the millivolt signal produced when two dissimilar metal wires join at a hot end. Same Read More
Paperless recorders are data loggers that record and trend measurement data over time — replacing strip-chart and circular recorders with a touchscreen, internal flash storage, and Ethernet/Modbus TCP/OPC UA export. Sino-Inst offers a variety of low pressure transducers for industrial Read More
A Type K thermocouple chart converts the millivolt output of a chromel/alumel junction into a temperature reading at 0 °C cold-junction reference. The chart is the IEC 60584-1 reference table — the same numbers used inside every Type K transmitter Read More
As a clean energy, natural gas is widely used in many aspects such as industrial production, thermal power generation and residential gas heating. Although natural gas pipeline transportation has many advantages, there are also risks such as leakage and failure. Read More
Updated May 29, 2026 · Sino-Inst Engineering Team A “standard” platinum rhodium thermocouple is not just a hotter thermocouple. It is a reference-grade device — first-class or second-class — whose whole job is traceable accuracy, so a calibration lab can Read More
Updated 2026-05-31 by the Sino-Inst Engineering Team A bimetal stemmed thermometer is only as accurate as its calibration and its immersion. Calibrate it to the 32°F (0°C) ice point. Push the stem at least 2 inches into the medium. And Read More
