9907-1198 second generation current-to-pressure converters

Description

Overview

Essential details：9907-1198 second generation current-to-pressure converters

Product Description

Woodward’s second generation current-to-pressure converters (CPC-II) 25 bar, Zone 2, simplex version with enhanced dynamics are electrohydraulic pressure regulating control valves used to position single-acting steam turbine valve servos/actuators.  The CPC-II solves one of the industries number one reliability issue of oil contamination affecting equipment uptime and performance.

The CPC-II accepts 4-20 mA pressure demand signals and accurately controls oil pressure to precisely position single-acting steam turbine governor-valves. Precise and stable steam valve control directly relates to improved steam turbine speed and load control and reduced system mechanical wear.

Features:

• Oil contamination resistant (ISO20/16)
• Precise fluid pressure control
• Stable & linear valve control
• Included valve linearization table (Full range <0.2%)
• Redundant inputs/sensors for critical applications
• Accepts signals from redundant controllers
• Redundant (dual) CPCs (Master/Slave) functionality
• Standard mounting and hydraulic connections
• Self-cleaning valve algorithm
• Status & health indication (Pressure transducer health, input demand signal health, internal unit health, Input power source quality)
• Control pressure readout
• Software service tool with trending
• Certified for North American Hazardous Locations
• Compliant with applicable CE Directives—ATEX, Machinery, PED, and EMC

Replaces:

• Woodward CPC’s: 8901-455, 8901-457, 8907-459, 9907-1102
• Voith E360 models

9907-1198 second generation current-to-pressure converters

The second generation current-pressure converter may refer to the second generation smart current-pressure converter, which is a device used to convert a current signal into a pressure signal.
Intelligent current-pressure converter is an intelligent pressure measuring instrument that integrates pressure measurement, display, output and control. It can convert 4-20mA current signal into 0-10V voltage signal or 20-100mV voltage signal, and also convert voltage signal into current signal.
Second-generation smart current-pressure converters typically have higher accuracy, lower noise, and higher stability, and can communicate and integrate with other smart devices. They are commonly used in industrial automation, process control, instrumentation and other fields.
