What is the function of a pressure transducer?
What is the function of a pressure transducer?
A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. Pressure transducers are used in many control and monitoring applications such as flow, air speed, level, pump systems or altitude.
How does a submersible pressure transducer work?
Submersible level transmitters consist of a sensor attached to a long cable, which is then lowered to the bottom of the liquid vessel. The sensor operates by measuring the hydrostatic pressure of the liquid medium. Also known as the head pressure, hydrostatic pressure is the pressure exerted by the fluid in the vessel.
How can a pressure transducer be used to measure level?
The principle of pressure transmitters, when used to determine fluid levels, is as follows: the pressure at the bottom of a fluid body is proportional to the height of the fluid above it. This is the hydrostatic head pressure, and is measured by the transmitter to obtain the fluid level reading.
What is pressure transducer in fluid mechanics?
Pressure transducers convert fluid pressure to an electrical signal for monitoring and control of pressure in electronic control systems. Pressure transducers have a sensing element of constant area and respond to force applied to this area by the fluid pressure.
What is the difference between pressure switch and pressure transducer?
A pressure switch is a simpler device that does not provide a continuous output. A pressure transducer converts the physical force of pressure into a continuous voltage output (V). The DC voltage output is typically amplified into industry-standard outputs such as 0-5V or 0-10V.
How does a level transducer work?
The transducer sends out an ultrasonic pulse. The pulse hits the surface of the liquid, and gets reflected. The sensor then calculates the fill level based on the time between the transmitted and received signal.
What is water level sensor?
Level sensors are used to detect the level of substances that can flow. Such substances include liquids, slurries, granular material and powders. Such meaurements can be used to determine the amount of materials within a closed container or the flow of water in open channels. …
What pressure does a pressure transducer measure?
Strain gauge pressure transducers are suitable to measure extraordinarily high and low pressures, as well as differential pressure. Differential pressure is the difference in pressure between any two given points. The transducer contains a sensing element, a diaphragm.
What are the types of transducer?
Types of Transducer
- Temperature transducers (e.g. a thermocouple)
- Pressure transducers (e.g. a diaphragm)
- Displacement transducers (e.g. LVDT)
- Oscillator transducer.
- Flow transducers.
- Inductive Transducer.
What is a KPSI 705 submersible transducer?
The KPSI 705 is a non-fouling submersible level transducer specifically designed to meet the adverse environments encountered in wastewater applications with a typical lead time of five business days or less.
What is the KPSI of the model accuracy?
Model Accuracy Description Image Minimum Full Scale Level Range Maximum Full Scale Level Range Output KPSI 30 KPSI 27 KPSI 28 ±0.10% FS ±0.25% FS ±0.50% FS General purpose, analog output 0-2 psi 0-1 psi 0-1 psi 0-2000 psi 4-20 mA, 0-5 VDC ACCESSORIES
What does KPSI stand for?
KPSI Transducers, Pressure Systems, Inc. Pressure Systems, Inc. is an ISO 9001: 2000 certified manufacturer of precision level and pressure instrumentation ranging from sensors to turnkey microprocessor-based systems.
How does a level and pressure sensor work?
KPSI™ Level and Pressure Transducers use isolated-diaphragm sensors that are specifically designed for use with hostile fluids and gases. These sensors utilize a silicon pressure cell that has been fitted into a stainless steel or titanium package with an integral, compliant stainless steel or titanium barrier diaphragm.
