Product Features |
Imported dry ceramic capacitive sensors are used. Good temperature characteristics and long-term stability. Obtain high reliability and measurement accuracy. |
|
|
On the basis of PMC133 standard pressure transmitter, an oil filled welded sealed isolation diaphragm structure is added. Avoid direct contact pressure of the medium |
|
|
The measuring diaphragm and sealing material of the force transmitter provide a reliable way for pressure measurement under special conditions. |
|
|
Oil filled welding sealing isolation device, with multiple different process connection structure forms and can be made of various materials, especially suitable for |
|
|
High temperature, low temperature, strong corrosion, high viscosity, and crystalline media; Suitable for clean and explosive hazardous environments. Having a negative table |
|
|
Pressure measurement. |
|
working principle |
As shown in the figure, the pressure of the measured medium is applied to the oil filled sealing isolation diaphragm, and the process pressure is applied to the sensor through the intermediate fluid. |
|
|
1Intermediate fluid inside the diaphragm membrane |
|
|
2Transmit pressure to the ceramic measuring diaphragm |
|
|
3The weak offset of the capacitor electrode results in a change in capacitance |
|
|
4. The connected circuit converts the change in capacitance into an electrical signal output |

electrical connection
Terminal block: M3 screw, cable: internal thread M20 * 1.5, cable sealing sleeve: external thread M20 * 1.5The function of a chain diode is to ensure the output current of the measuring instrument without cutting off the signal line during operation.
The wiring terminal with on-site display transmitter is placed at the back of the on-site display, and the display is connected through a metal socket and
When connecting the flexible cable to the transmitter, please gently pull up the monitor and plastic bracket together with the user's wiring
[Caution: Do not apply too much force to avoid disconnecting the flexible cable], the wiring terminal can be exposed.
[See the diagram of zero and range adjustment for details]
load characteristic
Zero point and range adjustment
The analog output type feed voltage is 13V to 30V [excluding the cascading diode, allowing for 12.5 to 30V voltage].The maximum load resistance depends on the instrument feed voltage.
