Description

The Ascenta MM818 module utilizes a thick-film piezoresistive circuit printed on a high-elasticity ceramic substrate. This construction provides inherent resistance to corrosion, abrasion, and media contamination, making it suitable for demanding fluid and gas pressure applications. The integrated signal conditioning chip converts the piezoresistive bridge imbalance into a stable, ratio-metric analog voltage signal.

Laser calibration and dynamic temperature compensation are applied to ensure long-term stability (≤0.15% FS/year) and minimal thermal drift across its extensive -40°C to +140°C operating range. The module’s patented circuit design offers robust electromagnetic compatibility (EMC) protection, ensuring reliable performance in electrically noisy industrial environments.

Key Features

  • Robust Ceramic Sensing Core: Features a wear-resistant, corrosion-proof ceramic diaphragm with a high modulus of elasticity for long-term stability and media compatibility.
  • Precision Signal Conditioning: Integrated ASIC provides laser-trimmed calibration for zero and span, delivering a highly linear 0.5-4.5V analog output proportional to the 5V supply.
  • Superior Environmental Durability: Engineered to operate reliably across a wide -40°C to +140°C temperature range with built-in protection against shock and vibration.
  • Advanced Thermal Compensation: Laser dynamic temperature compensation minimizes output drift, ensuring consistent accuracy under varying thermal conditions.
  • Industrial-Grade EMC Robustness: Patented circuit layout and design provide comprehensive electromagnetic compatibility, preventing interference in complex electrical systems.
  • High-Value Build: Optimized performance-to-cost ratio for applications requiring reliable pressure measurement without the expense of ultra-high-end transmitters.

Applications

  • Industrial Pump & Compressor Monitoring: Real-time pressure feedback in water booster pumps, hydraulic power units, and air compressor systems to prevent dry-running or over-pressure conditions.
  • HVAC System Control: Measuring refrigerant or chilled water pressure in heating, ventilation, and air conditioning systems for efficient flow regulation and fault detection.
  • Process Line Instrumentation: Integration into PLC-controlled industrial processes for monitoring liquid or gas pressure in pipelines, tanks, and reaction vessels.
  • Mobile Hydraulic Equipment: Pressure sensing in construction, agricultural, or material handling machinery for load monitoring and system safety.
  • Test & Measurement Rigs: Providing calibrated analog pressure input for data acquisition systems in laboratory or quality control environments.

Frequently Asked Questions

What is the output signal type and range of the Ascenta MM818 sensor?

The Ascenta MM818 provides a ratio-metric analog voltage output. When supplied with 5V DC, the output signal ranges from 0.5V at 0 bar pressure to 4.5V at the full-scale 10 bar pressure. This linear output is directly proportional to the applied pressure and the supply voltage.

What is the required supply voltage and can I use a 3.3V or 12V power source?

The module is designed for a nominal 5V DC supply. Operating outside this specified voltage, such as with 3.3V or 12V, is not recommended as it will affect the calibration, accuracy, and safe operation of the internal signal conditioning circuitry, potentially damaging the sensor.

How do I connect and interface this pressure sensor module with an Arduino or PLC?

Connect the module's 5V and GND pins to your system's power supply. The analog output pin should be connected to an analog input (ADC) channel on your microcontroller (e.g., Arduino) or to a voltage input module on your PLC. The 0.5-4.5V signal can be directly read and scaled to the corresponding pressure value in your software.

Is the MM818 sensor suitable for use with liquids like water or oil?

Yes, the ceramic piezoresistive sensing element is inherently corrosion-resistant and compatible with many common media, including water, oils, and non-aggressive gases. Its robust ceramic diaphragm and sealed construction make it suitable for direct use in hydraulic systems, water pumps, and similar liquid pressure applications.

Does the sensor require calibration, and what is its long-term stability?

The module is factory laser-calibrated for zero and full span, so no user calibration is typically required for initial use. It features excellent long-term stability, specified at ≤0.15% of full scale per year, meaning its calibration drift over time is minimal under normal operating conditions.
