Updated: May 10, 2026 — by Sino-Inst Engineering Team A zirconia oxygen sensor reads the O₂ partial pressure in a hot gas stream by exploiting yttria-stabilised zirconia, an oxide ceramic that becomes an O²⁻-ion conductor above ~600 °C. In flue-gas Read More
Contents Six technologies for powder level measurement Why powders are harder than liquids Radar for powders: 80 GHz, 26 GHz, and guided wave Vibrating fork and rotary paddle for point level Capacitive, RF-admittance, and ultrasonic alternatives Point level vs continuous 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
Updated 2026-05-09 by the Sino-Inst engineering team. A flow transmitter is the field instrument that turns a flow measurement into a 4-20 mA, HART, Modbus, or pulse signal that a PLC or DCS can read — and that a SCADA 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
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
A refrigerant flow meter must do something a water flow meter does not: handle a fluid whose density swings from 30 kg/m³ in the suction line to over 1300 kg/m³ in the liquid line of the same chiller. That density Read More
Choosing an ultrasonic level sensor for diesel tanks is a tank-geometry problem before it is a sensor-spec problem. The same 4–20 mA transmitter that reads cleanly on a 3 m vertical cylindrical AST can drift, foam-out, or echo the wrong Read More
Molten salt level measurement is one of the few level applications where the wetted-part metallurgy matters more than the sensor principle. At 565 °C in a concentrated solar power (CSP) cold tank — that is the cold side — solar Read More
