Overview
The fully automatic reset pressure control switch will automatically activate when the pressure in the fire sprinkler pipeline is lower than the pressure at the water supply end, and feedback the action signal back to the fire automatic alarm system host. The control host receives a signal to activate the fire sprinkler pump for pressurization.
Product Details
Fully automatic reset pressure control switchPurpose:
1. Electronic pressure switches amplify pressure signals through high-precision instrument amplifiers, collect and process data through high-speed MCUs, and compensate with built-in precision sensors. They are high-precision devices that detect pressure and liquid level signals, achieve pressure and liquid level monitoring and control.
2. Widely used in automation systems for measuring gas and liquid pressure in chemical, mechanical, hydrological, electrical, environmental protection, and other fields. Due to its convenient and flexible adjustment, as well as simple installation, it can replace most situations where liquid level switches are used.
3. The core of the product adopts a new type of intelligent microprocessor chip, which has practical and stable functions.
4. The LED displays the current pressure or liquid level value.
5. The pressure or liquid level can be set to start or stop according to one's own needs.
6. Three units of four LED products can be selected according to customer needs: Mpa, KG.F/CM2, PSI.
7. High and low pressure or liquid level alarm points can be set and output to the control equipment through relays or optocouplers; Output dual relay (single pole double throw) switch quantity.
8. Two relays/two optocouplers/with 4-20mA/0-10V output available for selection.
9. Adopting high-precision pressure sensors, with higher accuracy than mechanical pressure switches, less hysteresis, fast response, stable and reliable; Adjusting without dead zone, the relay action pressure point can be set arbitrarily within the entire range.
10. Using buttons to adjust action pressure, easy to use and more flexible; Protection level: IP65, suitable for use in harsh environments.

Fully automatic reset pressure control switchNotes:
1. The necessity of explosion-proof: Explosion proof forms are divided into explosion-proof and intrinsic safety types, and most Nagano products are explosion-proof.
2. Do you need instructions: According to customer instructions.
3. Number of contacts: one contact (one output) or two contacts (two outputs).
4. Determination of set value and pressure range: It is recommended to set the range between 30% and 65% of the pressure range, and the range can be set between 15% and 90% of the pressure range.
5. Types of connection and disconnection: adjustable or fixed.
6. Whether there is pulsation: If there is pressure pulsation or vibration, a throttle valve needs to be installed to suppress the damage of pulsating pressure to the instrument.
7. occasions with diaphragm: When measuring corrosiveness, high viscosity, or high temperature, it is necessary to use a diaphragm.
