- Ship propulsion auxiliary control panels
- Land-based industrial power control panels with high vibration
Material Composition:
- Front Frame: Self-extinguishing UL94 V0 flame retardant plastic
- Housing: Impact resistant reinforced plastic
- Measuring Mechanism: Permanent magnet moving coil assembly
- Scale Plate: Anti-corrosion coated metal plate
- Terminals: Tin plated copper screw terminals
Structural Features:
- Square panel mounting design following DIN 43700 standard
- Transparent scratch-proof front window
- Rear mounting clips for fixed installation
- Rear terminal block for input signal wiring
- Internal shock absorption structure for vibration isolation
Working Principle: External analog or pulse signal enters the instrument. Internal circuit converts signal to proportional DC current for moving coil mechanism. Magnetic field generates torque to rotate pointer against restoring spring. Pointer position directly indicates measured value on printed scale. Rear potentiometer adjusts signal gain to calibrate full scale reading.
Installation Requirements:
- Mount on control panel with standard 144mm cutout
- Fasten mounting clips symmetrically to avoid casing stress
- Separate signal wiring from high voltage power cables
- Avoid installation location with strong magnetic field
- Maintain gasket integrity to preserve front panel protection rating
Usage Notes:
- Complete full scale calibration after wiring and power on
- Do not apply voltage or current exceeding rated input range
- Prevent salt mist and humidity entering instrument housing
- Check pointer zero position periodically
- Disconnect all input signals before removing instrument
