Description
Foxboro P0700TT
Technical Specifications
- Input Types: RTD, Thermocouple, mV, V, mA.
- Channels: Single or multiple channels.
- Output: Standardized signal for the DCS.
Functional Features
- Direct Sensor Connection: Eliminates the need for external transmitters for temperature measurements.
- Built-in Linearization: Automatically linearizes thermocouple and RTD signals.
- Burnout Detection: Detects open sensor circuits and drives the output to a configurable fail-safe state.
Application Scenarios
Ideal for temperature monitoring and control in ovens, reactors, heat exchangers, and storage tanks.
Performance Parameters
- Accuracy: High-accuracy temperature measurement.
- Response Time: Fast thermal and electrical response.
Material Composition
Precision resistors and analog ICs for stable temperature measurement.
Structural Characteristics
Compact module with terminal blocks for direct sensor wiring. Status LEDs indicate power and sensor health.
Working Principle
Provides excitation to the sensor, measures the resulting voltage or resistance, performs linearization and cold-junction compensation (for TCs), and outputs a scaled engineering value to the DCS.
Installation Requirements
Use the correct type of extension or compensation wire for thermocouples. For RTDs, use 3-wire or 4-wire configuration to cancel lead wire resistance.
Usage Precautions
- Ensure the sensor type is correctly configured in the DCS.
- Keep temperature sensor wires away from high-voltage power cables.
