IS 20s wika?
The WIKA IS-20 and IS-21 series of intrinsically safe pressure transmitters are designed for industrial pressure measurement applications in hazardous areas where intrinsically safe ratings are required. These multiple approvals provide for global recognition and acceptance of the intrinsically safe ratings.
What do pressure transducers do?
A pressure transducer is a device which converts an applied pressure into a measurable electrical signal which is linear and proportional to the applied pressure.
How is a pressure transmitter installed?
Pressure transmitter installation If you have an open tank, then you can install the device on the bottom of the tank using a flange with a filled-sealed container. If you want to measure flow with a pitot, then you can install the device using a single flange direct to the pitot.
How do you calibrate a pressure transducer?
To calibrate your software-controlled sensor you will need to:
- Connect the sensor to the control software.
- Accurately apply zero and full-scale pressure to the transducer.
- Using the software, adjust the zero and full-scale output calibration variables until the respective outputs of the sensor are correct.
What is potentiometric pressure sensor?
The potentiometric pressure sensor provides a simple method for obtaining an electronic output from a mechanical pressure gauge. The device consists of a precision potentiometer, whose wiper arm is mechanically linked to a Bourdon or bellows element.
Where should a pressure transmitter be installed?
How does a pressure transmitter work?
The functional principle of a resistive pressure transmitter is very simple. The diaphragm is deflected under the influence of pressure. Thus, the strain gauges attached to it are elongated or compressed and its electrical resistance changes. This change in resistance is directly proportional to the pressure.
Can you calibrate a transducer?
To calibrate your software-controlled sensor you will need to: Connect the sensor to the control software. Accurately apply zero and full-scale pressure to the transducer. Using the software, adjust the zero and full-scale output calibration variables until the respective outputs of the sensor are correct.
What are the different types of pressure sensors?
Different Types of Pressure Sensors
- Strain Gauge – Chemical Vapor Deposition Pressure Sensors.
- Strain Gauge – Sputtered Thin Film Pressure Sensors.
- Variable Capacitance Pressure Sensors.
What is pressure sensor and its types?
Table
| System requirement | Sensor technology | |
|---|---|---|
| Metal thin-film | Piezoresistive | |
| Absolute pressure measurement | No | Yes |
| Very low pressure range | No | Yes |
| Very high pressure range | Yes | No |
What do Wika IS-20 and IS-21 pressure transmitters do?
The WIKA IS-20 and IS-21 series of intrinsically safe pressure transmitters are designed for industrial pressure measurement applications in hazardous areas where intrinsically safe ratings are required.
What kind of process connection does Wika IS-20 have?
The IS-20 includes an NPT process connection while the IS-21 transmitters feature a flush diaphragm process connection specifically designed for the measurement of viscous fluids or media containing solids that may clog a NPT process connection.
What is the PSI range of Wika S-20?
It features a very good accuracy, a robust design and an exceptional number of variants, meaning it can be suited to the widest range of applications. The model S-20 offers continuous measuring ranges between 0-5 to 0-20,000 psi in all the major units.
