Product Features
1. Four LED displays the current pressure value without visual field error.
2. The on-site setting of four-way control points can set high and low pressure or liquid level alarm points, and the delay switching output time can be set by oneself and output to the control equipment through relays.
3. Key calibration and on-site setting of high and low limit values and alarm parameters.
4. There is no dead zone in liquid level regulation, and the relay action can be set arbitrarily within the entire range.
5. The liquid level point can be adjusted by pressing the button to adjust the action liquid level, which is easy to use..
6. Adopting high-precision AD and high-speed processor, fully digital design. 7. Optional output switch quantity form, input power supply.
8. One analog output (4-20mA, optional), or one RS485 output (optional).III
