Overview
The NOSHOK PT20-30PSIC-1-5-2-25-ST8-CC is a pressure transmitter featuring a 30 PSIC measurement range. It utilizes a silicon piezoresistive sensor element for accurate signal conversion. The device provides a 4-20 mA analog output signal, powered by a 10-30 VDC supply voltage. It incorporates an RS-485 digital interface supporting Modbus RTU protocol for advanced communication capabilities. The unit is housed in a stainless steel construction with a 1/4 inch NPT process connection and includes a cable outlet configuration.
Feature Summary
- Dual-mode operation combining standard analog current output with digital serial communication capabilities
- Robust stainless steel housing designed for industrial durability and corrosion resistance
- Integrated temperature compensation to maintain accuracy across varying thermal conditions
- Flexible connectivity options including both analog loop power and digital data transmission
Applications
- Industrial process control systems requiring precise pressure monitoring
- Hydraulic and pneumatic machinery feedback loops
- HVAC system pressure regulation and diagnostics
- Oil and gas pipeline monitoring stations
Procurement Notes
Verify the specific process connection thread size and material compatibility against your installation requirements. Confirm that the required communication protocol settings align with your existing controller or PLC infrastructure. Ensure the supply voltage range matches your available power distribution network. Check for any special calibration certificates if regulatory compliance is mandatory for your application environment.
Selection Notes
Choose this model when both analog and digital outputs are necessary for system redundancy or advanced diagnostics. Consider the environmental temperature range and media compatibility before deployment. Evaluate the need for remote configuration capabilities provided by the digital interface. Assess the physical space constraints regarding the cable outlet orientation and overall dimensions.
Part Context
This component belongs to the NOSHOK PT20 series of pressure transmitters. The series is characterized by high reliability and versatility in demanding industrial environments. Other models in the family may offer different pressure ranges, output types, or process connections while maintaining similar core performance standards and construction quality.
Replacement Considerations
Direct cross-replacement requires matching the 30 PSIC range, 4-20 mA output, and RS-485 Modbus functionality. Verify mechanical fitment including the 1/4 NPT port and mounting style. Consult manufacturer documentation for updated part numbers within the same product line.
