FAQs
What pressure ranges and accuracy levels are available for PX300?
The PX300 covers pressure ranges from vacuum (-100~0 kPa) up to high pressure (0~60 MPa). It offers selectable accuracy classes of 0.5% FS (standard), 0.25% FS, and 0.2% FS to meet diverse precision requirements.
What output signals and power supply voltages does it support?
It supports standard 2-wire 4-20mA (10-32VDC), analog voltage 0-5V / 1-5V (8-32VDC), 0-10V (12-32VDC), and digital RS485 Modbus-RTU (8-32VDC / 17-32VDC with display).
Is the PX300 suitable for liquid cooling data centers?
Yes. The PX300 is engineered specifically for liquid cooling data center loops and HVAC water systems. Its 316L stainless steel wetted diaphragm ensures superior resistance against coolant and treated water.
What process connections and thread standards are supported?
Standard process connections include M20*1.5 male thread, G1/2 male thread, G1/4 male thread, NPT 1/2, and NPT 1/4. Custom thread specifications can also be provided upon request.
What is the ingress protection and operating temperature range?
The standard model features IP65 ingress protection (with IP50 display head), and an IP68 waterproof version is available. It operates reliably in ambient and medium temperatures from -20°C to +85°C.
Can the transmitter withstand pressure overloads and surges?
Yes. It provides 150% FS overload capability for ranges up to 10 MPa and 125% FS for ranges between 10~60 MPa, along with comprehensive EMC surge and ESD protection (IEC61000-4 series).
