HVAC/Refrigeration Pressure Sensor, 4-20mA/0-5V

HVAC/refrigeration pressure sensors for sale online support liquid or gas media measurement and offer a variety of pressure ranges, including 0-0.6/0.8/1/1.4/1.6/1.8/2.5/3/4 MPa. Output signals include 4-20mA, 0-5V, and 1-5V. SUCH refrigeration pressure sensors utilize a 316L stainless steel diaphragm and housing, are IP65 rated, operate stably in temperatures ranging from -40°C to 85°C, and are resistant to 10g vibration and 500g/ms shock. The compact design, lightweight, and easy installation make them durable and reliable, making them suitable for a variety of refrigeration and air conditioning applications.

Feature

• Refrigerated pressure sensor utilizes selected high-quality wafers for minimal thermal drift and high stability.
• It utilizes laser-processed, fully metal-sealed design for enhanced corrosion resistance.
• Internal sealing treatment ensures moisture and vibration resistance.
• The housing is constructed of 316L stainless steel for durability and adaptability to harsh environments.
• The double-layer circuit design enhances electromagnetic compatibility.
• The compact design makes installation easier.
• It features a built-in pulse snubber to effectively reduce transient overpressure shocks.

Wiring Diagram

Note:

Circles represent shielded wires, and all marked grounding points must be effectively grounded. It is recommended to use shielded twisted signal cable. In order to avoid ground loops, the shielding layer using a single-ended ground, in the pressure transmitter end of the insulation floating ground, and in the control cabinet end of the ground.

The pressure transmitter shell is grounded by default, so the field equipment needs to be effectively grounded, if the field equipment can not be grounded, it is necessary to make the indicated grounding point effectively grounded.
