Product Advantages
1
Precise Measurement & Control with Rapid Response: Equipped with a 3.5-digit 7-segment display, the display accuracy reaches ±0.5% F.S.± 1-2 digits, and the repeatability accuracy is ±0.1% F.S. It can accurately capture pressure data. The response time is only 1ms, enabling real-time monitoring of pressure. It also has the function of preventing oscillation and can adjust the response time by setting different parameters, making it suitable for volatile pressure scenarios.
2
Practical Display & Rich Functions: Supports red/green dual-color display, and can set four display modes. Combined with action indicator lights, it can visually distinguish the working status. It features practical functions such as automatic presetting, peak/valley display, zeroing, and key lock. Some models support switching among seven pressure units to meet the reading and operation requirements of different scenarios. Additionally, it has an error display function for easy troubleshooting.
3
Strong Adaptability & Convenient Connection: Compatible with multiple series of sensors such as MK56, it supports DC1-5V voltage input or DC4-20mA current input. The output can be selected as NPN or PNP dual output, and can be matched with 1-5V voltage output or 4-20mA current output, meeting various signal requirements. It adopts the plug connection method. The accessories include dedicated connection cables and plugs, simplifying the wiring process.
4
Flexible Installation & Reliable Protection: It supports horizontal and vertical close-fitting installation, and can also achieve panel installation, bracket installation and DIN rail installation, significantly saving installation space and reducing working hours. The protection grade reaches IP40, featuring reverse power connection protection and output short-circuit protection. It operates within a temperature range of 0–50℃ and a humidity range of 35–85% RH. It is suitable for conventional working conditions such as industrial control cabinets and complies with standards like CE and RoHS, ensuring stable operation.
