ESMDPS 4-20mA differential pressure transmitter / sensor
Company Profile
The company's main pressure transmitters, level gauge, ultrasonic sensors, load cells, torque sensors, temperature sensors, flow meters, photoelectric sensors, proximity sensors, smart display controller and a variety of accessories and other products.
Working principle
ESM series silicon piezoresistive differential pressure sensor is a kind of used for measuring the differential OEM differential pressure oil filled core body. Sensitive element structure of integration, high static pressure resistance value, solid and reliable. High and low pressure side adopt isolation membrane protection, two pressure chamber can remove has certain corrosion resistance and electrical conductivity of the fluid medium, differential pressure being measured by isolating diaphragm and filling silicone oil is passed on to the silicon pressure sensor, realized the precise measurement of the differential pressure.

Pressure connection
Differential pressure transmitter has two intake ports, a high pressure gas inlet, marked as: H; a low pressure inlet, logo: L during the installation process, do not allow oil leakage phenomenon, leakage may exist. the measurement accuracy is reduced. Pressure ports commonly used G1 / 4 (internal), G1 / 4 (outside), 1 / 4NPT (outside), 1 / 4NPT (inside). Hydrostatic pressure over both ends ≤2.8MPA, high pressure short time overload pressure ≤3 times the rated pressure.
Wiring definitions
Here Xi'an Electronic Science and Technology Co., Ltd. Min wave Disclaimer: whatever is written in accompanied by a simple wiring instructions of our products will be in the product package. So I ordered all the products to customers, you can just get the product wiring. It does not require any electrical knowledge, as long as I can carry out the company's wiring.
Instruction manual:
differential pressure transmitter, small size, light weight, the installation can be installed directly at the measuring point, pay attention to check the tightness of the pressure port, to prevent leakage and affect measurement accuracy.
An defined according to the wiring connected wires, transmitters can enter the working state. For high precision measurements, the instrument should be energized after half an hour and then enter the work state.
Maintenance instructions:
Transmitter normal use without maintenance.
If you need to check the transmitter, there should be professionals to operate, if necessary returned for verification, I committed no fee check.
instrument when not placed 10-30 Celsius, humidity of 30% -80% of a clean environment preservation.
Precautions:
Transmitter proposes to add two-way valve in the installation, in order to prevent excessive pressure at both ends of the transmitter by the pressure.
differential pressure transmitter should be used in 316L stainless steel diaphragm for non-corrosive gas or liquid.
wiring is in strict accordance with the wiring should be defined to ensure that the transmitter wiring normal use.
field interferences or demanding situations, use a shielded cable.
