Reliable Measurement Capability In Extreme And Harsh Working Conditions - Split Type Pressure Transmitter
A split type pressure transmitter refers to a transmitter where the pressure sensor (also known as the "diaphragm" or "sensor head") and the signal transmitter (electronic component) are physically separated and connected through a capillary tube and filling liquid system.
The split design is aimed at addressing extreme working conditions that integrated transmitters cannot handle. Its value is reflected in the following scenarios:
Compared with the core of the integrated pressure transmitter
| Characteristics | Split pressure transmitter | Integrated pressure transmitter |
|---|---|---|
| Structure | The sensor (remote flange) and the transmitter are separated, connected by a capillary tube. | The sensor and the transmitter are integrated into one. |
| Installation | Complex. Requires installation of flanges, laying and fixing of capillary tubes, and connection of the transmitter body. | Simple, directly installed at the pressure tapping point. |
| Response speed | Slow. Affected by the length, diameter of the capillary tube and the nature of the filling liquid, there is obvious lag. | Fast, direct signal. |
| Reliability | Increased potential risk points. The capillary tube may leak, clog, or suffer mechanical damage; the filling liquid may cause additional errors due to temperature changes. | High, fewer connection points, lower failure rate. |
| Maintenance | Complicated. Fault diagnosis is complex (is it the flange, the capillary tube, or the transmitter problem?), and maintenance requires handling the filling liquid system. | Convenient, overall replacement. |
| Cost | Expensive. The equipment itself is expensive, and the comprehensive cost of installation and maintenance is high. | Economical, low comprehensive cost. |
| Applicability | Solution for special working conditions (high temperature, corrosion, vibration, etc.). | Preferred for the vast majority of conventional working conditions. |
Split-type pressure transmitters are the "special forces" in pressure measurement technology. They trade off response speed, increase system complexity and cost, in exchange for the ability to perform reliable measurements under extremely harsh conditions.
