Pressure Transmitters Pressure transmitters are instruments used in industrial automation
to measure pressure and convert physical pressure signals into
standard electrical signals. They are widely applied in almost all
process industries such as petrochemical, power, pharmaceutical,
and food industries, and are core sensing devices for ensuring
production safety and process stability. Core Advantages Features Explanation - Good stability: Adopting imported original sensors and dedicated V/I integrated
circuits, it is reliable for long-term operation.
- Strong anti-interference: 4-20mA two-wire current signal, suitable for long-distance
transmission (up to thousands of meters).
- Wide medium compatibility: Compatible with oil, water, corrosive liquids, viscous media, etc.
- Compact structure: Small in size, light in weight, and easy to install and debug.
- On-site readable: Optionally equipped with LED, LCD or pointer heads for convenient
on-site viewing.
In terms of service life: High-quality pressure transmitters are
generally designed to withstand maximum pressure for up to 200 million pressure cycles without performance degradation. Common classification methods | Classification dimension | Example types |
|---|
| By measurement principle | Capacitive, diffused silicon piezoresistive, single crystal
silicon, ceramic capacitive | | By output signal | 4-20mA type, voltage type, digital communication type | | By accuracy | High accuracy (0.1% and below), general accuracy (0.5%) | | By measurement range | General pressure transmitter, differential pressure transmitter,
negative pressure transmitter | | By explosion-proof grade | Extrinsic safety type, flameproof type, non-explosion-proof type |
If you need specific type recommendations based on your working
conditions, please provide me with parameters such as the measured
medium, pressure range, temperature, and accuracy requirements, and
I can help you analyze further. |
