4-20ma 0-5v air hvac refrigeration pressure sensor air pressure transducer
HDP501 series high temperature resistant pressure transmitter pressure sensitive core adopts high performance silicon pressure resistance to fill the core. The internal ASIC conversion sensor's millivolt signal is converted into standard voltage, current or RS485 signal, with strong photoelectric isolation to ensure stable output. It can be directly connected to a computer, digital display or PLC. Can withstand 200 ° C high temperature, all stainless steel sealed structure, can be used in corrosive environment. The product is easy to install and has high vibration and shock resistance. It is widely used in control, aviation, aerospace, automotive, medical equipment, HVAC and other fields.Technical Parameters
