GE 5KC35KG198
GE 5KC35KG198 is a high-precision temperature sensor module under the Industrial Automation Series of General Electric (GE). It is specifically designed for process control, equipment monitoring, and energy management systems. This module is used for accurate temperature measurement (usually used in conjunction with thermocouples or RTDs) and converts signals into standard outputs (such as 4-20mA) for use in PLC, DCS, or SCADA systems. It is suitable for temperature monitoring in fields such as power, petrochemical, and manufacturing industries.
Product Parameters
- Product Model: 5KC35KG198
- Manufacturer: General Electric (GE)
- Product Type: Temperature Transmitter / Signal Conditioning Module
- Input Signal Type: Thermocouples (Type J/K/T), RTD (PT100), millivolt signals
- Output Signal: 4-20mA (two-wire system), 0-10V DC (three-wire system)
- Measurement Accuracy: ±0.1% FS (for 4-20mA output)
- Isolation Voltage: 1500V AC (between input/output/power supply)
- Operating Temperature Range: -40°C to +85°C (-40°F to +185°F)
- Protection Class: IP20 (must be installed in a control cabinet)
- Installation Method: DIN Rail mounting
- Power Supply Voltage: 12-36V DC (for two-wire 4-20mA) or 24V DC (independent power supply)
- Power Consumption: ≤1.5W (typical)
- Certification Standards: UL 508, CE, IEC 61010-1
Key Features and Advantages
1. High Precision and Stability
- It has an accuracy of ±0.1% FS, suitable for precision temperature control (such as reactor temperature management).
- Equipped with automatic cold junction compensation to eliminate the impact of ambient temperature on thermocouple measurement.
2. Anti-Interference Capability
- 1500V AC isolation to suppress ground loop interference and on-site noise.
- EMC design that complies with IEC 61326 standards (EMC requirements for industrial environments).
3. Flexible Configuration
- Input types (J/K/T type thermocouples, PT100) can be configured via DIP switches or software.
- Supports custom ranges (e.g., -50°C to 200°C corresponding to 4-20mA).
4. Industrial-Grade Durability
- Wide temperature operation from -40°C to +85°C, adapting to extreme environments.
- Passive components (such as resistors and capacitors) are made of industrial-grade materials to ensure long-term stability.
Application Fields
5KC35KG198 is mainly used in the following scenarios:
-
Power Industry:
Boiler temperature monitoring (e.g., superheater, reheater outlet temperature).
-
Petrochemical Industry:
Temperature monitoring of reactors and pipelines (safety barriers must be installed in explosion-proof areas).
-
Manufacturing Industry:
Temperature control of injection molding machine barrels and temperature monitoring of heat treatment furnaces.
-
HVAC:
Water temperature and air temperature measurement in central air-conditioning systems.
Installation and Maintenance
Installation Points
- Shielded twisted pairs should be used for sensor wires, and the shielding layer should be grounded at one end (on the control cabinet side).
- Avoid parallel routing with power cables (minimum spacing of 30cm).
Maintenance Recommendations
- Calibrate once a year (using a standard temperature source and a precision ammeter).
- Check for loose terminals (poor contact is likely to occur in vibrating environments).
