A pressure transmitter is a type of sensor that converts pressure into a standard electrical signal. When selecting a pressure transmitter, it's essential to consider several key factors to ensure the right choice for your specific application. Here are the main points to evaluate:
1. **Determine the Type of Pressure Measurement**
The most common types are gauge pressure, absolute pressure, and differential pressure. Gauge pressure measures pressure relative to atmospheric pressure (either above or below it). Absolute pressure is measured from a perfect vacuum, while differential pressure refers to the difference between two pressures.
2. **Confirm the Accuracy Level**
The accuracy of a pressure transmitter is defined by its error margin, which is usually expressed as a percentage of the full-scale output. The selection should be based on the required precision of your application and the cost-effectiveness of the solution.
3. **Check the Operating Temperature Range**
The transmitter must operate within the temperature range of the medium being measured. Exceeding this range can lead to significant measurement errors and reduce the device’s lifespan. Some transmitters are designed with built-in temperature compensation, while others may require external cooling solutions like condensing tubes or radiators in high-temperature environments.
4. **Ensure Compatibility Between Media and Materials**
In applications involving corrosive or chemically aggressive media, it's crucial to select materials that are compatible with the measured substance. Special coatings or treatments may also be necessary to prevent damage to the transmitter.
5. **Confirm the Pressure Connection Type**
Most of our products use a threaded connection (M27 × 2) as the standard interface. However, we can customize the connection type based on customer requirements.
6. **Select Power Supply and Output Signal**
Our pressure transmitters are typically powered by DC 24V and offer multiple output options, including 4–20mA, 0–5VDC, 1–5VDC, and 0–20mA with RS485 digital communication.
7. **Evaluate On-Site Working Conditions**
Consider environmental factors such as vibration, electromagnetic interference, and other site-specific conditions. These can affect performance, so appropriate measures should be taken during selection. Additional considerations like wiring configurations may also be needed depending on the application.
By carefully evaluating these factors, you can ensure the best performance and reliability from your pressure transmitter. For more information or custom designs, feel free to contact us directly.
