Daytronic 4077 Series DC Strain Gauge Controller

Daytronic 4077 Series DC Strain Gauge Controller

The Daytronic 4077 Series DC Strain Gauge Controller is a high-performance instrument designed for precise measurement and control in industrial applications. Engineered to accommodate conventional 4-arm strain gauge bridges with nominal resistances ranging from 90 to 2000 Ohms, this controller ensures accurate and reliable data acquisition.

Key Features

• Excitation Supply: Provides regulated 5 or 10 V-DC excitation, selectable by the user, ensuring consistent and stable power to the strain gauge.
• Analog Outputs: Equipped with three analog outputs, each offering ±5 V full-scale with 50% overrange capability. These outputs feature low-pass corner frequencies of 2 Hz, 200 Hz, and 2 kHz, respectively, catering to various signal processing needs.
• Common-Mode Rejection: Boasts a common-mode rejection ratio greater than 80 dB, effectively minimizing interference from external noise sources.
• High Input Impedance: With an input impedance exceeding 100 megohms, the controller preserves the integrity of factory calibration and mitigates errors due to cable resistance.
• Advanced Filtering: Incorporates active low-pass filters that provide -60 dB per decade attenuation above the cutoff frequency, effectively smoothing out unwanted dynamic signal components arising from vibration or power impulses.
• Chopper Stabilization: Utilizes solid-state chopper stabilization techniques to eliminate both short-term and long-term drift, ensuring stable and accurate measurements without the need for warm-up periods or frequent recalibration.

Physical and Environmental Specifications

• Power Requirements: Operates on 110/220 VAC at 50-400 Hz, with a power consumption of 30 W, making it suitable for various industrial power environments.
• Construction: Housed in a robust, heavy-gauge aluminum case measuring 1.7” H x 4.41” W x 7.0” D, designed for durability and ease of integration into existing systems.
• Operating Temperature Range: Functions reliably within a temperature range of 0°F to +130°F (-18°C to +55°C), accommodating diverse industrial settings.

The Daytronic 4077 Series DC Strain Gauge Controller stands as a reliable and efficient solution for professionals seeking precise strain measurement and control in demanding industrial applications.
