| Product Introduction
The WCPS300-X1 series [angled display head] electronic digital pressure switch/transmitter is a new-generation intelligent pressure measurement and control product independently developed by winchen sensor. It integrates real-time pressure measurement, high-definition digital display, flexible switch control and standard analog transmitter output, and uses a high-quality imported pressure sensor core to ensure long-term stability and reliability. It is widely used in hydraulic, pneumatic, water pump and industrial automation fields. The product is equipped with a high-brightness 4-digit LED digital tube display. Users can perform range setting, zero/full-scale calibration, alarm point setting and other operations on site through the panel buttons, with no additional handheld device required, greatly improving on-site commissioning and maintenance efficiency.
| Functional Features
1. Angled display-head ergonomic design: the unique angled display panel offers a friendly reading angle, effectively avoiding the inconvenience of reading when the installation position is too high or too low, significantly improving the on-site inspection experience.
2. High accuracy and high stability: using an imported diffused silicon core, with an accuracy class of up to±0.5%FS; excellent long-term stability and low temperature drift, suitable for complex industrial environments.
3. Multi-function output combination: supports switch output (2 channels, PNP/NPN configurable) + analog output 4-20mA, meeting the connection needs of different systems.
4. On-site programmable operation: built-in multi-level menu; range migration, switching, output mode setting, delay time adjustment, etc. can be completed through the panel buttons, with simple and intuitive operation.
5. Excellent anti-interference and protection performance: high-quality engineering plastic display-head housing with IP65 protection rating, featuring multiple safety mechanisms such as reverse polarity protection, overvoltage protection and short circuit protection, adapting to harsh on-site environments.
6. Compact structure, flexible installation: M20×with thread connections such as 1.5 and G1/4, it can directly replace traditional mechanical electric contact pressure gauges, and supports axial and radial installation methods, greatly reducing retrofit and upgrade costs.
