Thermocouple alloy and junction selection
Digital Pressure Gauge: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
The archived configuration for Digital Pressure Gauge lists Nominal diameter: Φ80/100. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For Digital Pressure Gauge, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of Digital Pressure Gauge depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

ARCHIVED PRODUCT INFORMATION
Description
Digital pressure gauges are precision instruments that use electronic sensors to measure and display pressure values digitally, offering higher accuracy and more functionality than traditional analog gauges.
| type | Digital pressure gauge |
| Nominal diameter | Φ80/100 |
| Measurement range | -0.1~0~60MPa |
| accuracy level: | 0.4% |
Core Features
High Precision: Typically achieve accuracy classes of 0.2, 0.4, or 0.5, far exceeding the 1.6 or 2.5 classes common in analog gauges.
Digital Display: Clear LCD or LED screens show readings directly (e.g., 0.000 MPa), eliminating parallax errors and making readings intuitive.
Multi-Unit Support: Allow seamless switching between pressure units like MPa, kPa, bar, psi, kg/cm², and inHg.
Smart Functions: Include features such as peak/valley tracking, data logging, zero calibration, automatic power-off, and communication outputs (e.g., RS485, 4-20 mA).
Power Options: Operate on internal batteries (for portability) or external DC/AC power (for fixed installations).

Key Components
Pressure Sensor: The core element, often a piezoresistive or capacitive sensor, converts pressure into an electrical signal.
Signal Processing Circuitry: Amplifies, filters, and converts the sensor signal into a digital value.
Display Module: Shows the pressure reading, battery status, and operational status.
Control Buttons: Enable power on/off, unit switching, zeroing, and menu navigation.
Process Connection: Stainless steel threaded fittings (e.g., M20×1.5, G1/2") for mounting to pipes or equipment.
Common Applications
Industrial Automation: Monitoring pressure in pipelines, pumps, and compressors.
Laboratory & Calibration: Precision pressure measurement and instrument calibration.
HVAC & Refrigeration: Controlling refrigerant and air pressure.
Oil & Gas: Wellhead and pipeline pressure monitoring.
Aerospace & Automotive: Testing hydraulic and pneumatic systems.
Selection Considerations
Pressure Range: Select a range that covers the maximum expected pressure with a safety margin (typically 1.5× the working pressure).
Accuracy Class: Choose based on the application's precision requirements (e.g., 0.2 class for calibration labs).
Media Compatibility: Ensure the wetted parts (e.g., stainless steel 316L) are compatible with the measured fluid or gas.
Environmental Conditions: Consider temperature range, vibration, and explosion-proof requirements (Ex-certified models for hazardous areas).
Output Options: Select analog (4-20 mA) or digital (RS485, Modbus) outputs for integration with control systems.
