Digital Instrumentation - RTD’s RTD Glossary RTD (Resistance Thermometer Detector) The industry-wide acronym for resistance thermometer detector is widely used to describe the RTD sensor which is a device comprising a resistive element (usually Pt100) which relies on the inherent change in resistance...
On many occasions in processing industries, it is not possible or desirable to insert a temperature sensor—that is, a thermocouple, RTD, bimetallic thermometer, glass stem thermometer, or filled system bulb—directly into the process material. A protective enclosure, called a “thermowell” or “...
Proper instrumentation is key to profitable plunger lift applications How to select hydraulic pressure gauge ranges Selecting pressure gauges: New advances on an old technology Mechanical vs digital or wireless pressure gauge What is RTD Sensor and How Does it Work? Pressure and Temperature Gauges Ge...
Temperature Sensor (Thermocouple, RTD): These devices can give a variable output voltage or current signal that is proportional to the temperature they are measuring. Flow Meter: Provides a variable voltage or current signal proportional to theflow rateof a fluid. ...
To eliminate the corresponding measurement error, the tube temperature is continuously measured by an RTD element and is used to continuously compensate for variations in tube elasticity. Coriolis mass flow meters usually are calibrated on water because the constants are valid for all other liquids....
Distance between the sensor and instrumentation. Type of interconnections the customer prefers. What type of wiring system is currently in place (if not new).RTD's are purchased with 2, 3 or 4 lead wires per element:RTD THEORYPage 3 is the of the 3 types since there is no way of...

In addition, Dinkle’s spring cage is easily operated, using press-to-release tabs, so users can install and remove any solid or stranded wires as needed without tools. Contact surfaces are wide, ensuring reliable operation at up to 300 V and 12 A (UL). The connectors are compliant with...
Dual-Band Operation: The standout feature of this module is its ability to simultaneously support both SUB-GHz (e.g., 433 MHz, 868 MHz, 915 MHz) and 2.4G frequency bands. This dual-band compatibility allows the same module to flexibly switch communication bands in different application scenar...
“Bumpless transfer” is a term used to describe the desired action a controller (PID, for example) is expected to maintain when transferring from manual to auto mode, or vice-versa. In auto mode, the controller calculates a deviation between the desired setpoint and the actual value of the...
