A guide to select your sensors/transducers/transmitters

Pressure sensors/transducers/transmitters are offered with a wide variety of configurable options, sizes and approvals. This article with the key features of pressure sensors design or construction is to take into consideration to select the appropriate sensor for your application.

1.Mechanical Interface

 The mechanical interface, also referred to as the process connection, is how the sensor is connected to the pressure source. This is typically done via a threaded connection. XIDIBEI offers a wide range of thread types including NPT, PT, SAE/UNF, G(BSP), DIN and Metric. Male and female versions are available. Certain factors may limit the availability of the process connections including material requirement and pressure range. Custom connection options are available upon request. Thread adapters to your request is also available.

2.Pressure Range

XIDIBEI offers the pressure sensor from -1 bar to 3,000 bar from a variety of pressure sensors, from Ceramic sensor, diffused sensor, micromelting sensors, strain sensors, and sputter sensor. It is recommended the appropriate sensors to different applications and requirements.

For instance, the sensors connected with water pump in water treat systems, it is advisable to use ceramic sensors with relieve/buffer valve.

3.Electrical Interface

The electrical interface, also referred to as the electrical connection, is how the output signal is transmitted to a PLC or other instrumentation. Electrical connection options include integral cable, connector or inline connector. You can choose from connectors such as Hirschman DIN 43650-A and C, M12x1(3 Pin, 4 Pin and 5 Pin), Packard, Plastic direct cable, Gland direct cable and others. Certain product families have a limited selection of options due to hazardous certifications and design limitations. Wire-to-cable connectors are available in-line installed directly at the sensor for retrofit applications. Custom configurations are available to your request.

The environment where the sensor will be installed should be taken into consideration. Different connection types offer different ingress protection (IP) ratings. XIDIBEI will be helpful to choose the suitable electrical connectors based on your installation environment.

4.The available power supply is another important factory to consider. It can narrow the output signals options.

XIDIBEI offers a wide options, 5-12VDC, 9-36VDC, in which 24VDC is the most common use. For long distance transmissions, it is recommended to use 4-20mA output signal(current signal not affected by distance).

There are multiple voltage signals available requiring different power supplies. For example, a 0-10V output signal requires a 12VDC/9-36VDC power supply while a 0.5-4.5V output signal requires a regulated 5VDC/12VDC power supply. 

 5.Process media

The process media is the gas/liquid in the application whose pressure is being measured. Understanding the process media will help guide the selection of the mechanical interface material and sometimes it will require a different process. Common material includes stainless steel 304, stainless steel 316L and 17-4PH, other alloy materials.

 6.Comprehensive accuracy

Understanding the comprehensive accuracy requirement is very important to choose the appropriate sensors according to the applications. It can also determine the sensor process.  

XIDIBEI offers high accuracy as 0.1%, 0.2%, and common accuracy 0.5%, 1% and others to your different requirements.
