Description

The Renke RS-NH3-N01-2-100P-2-YL-EX employs a high-sensitivity electrochemical sensing principle for accurate ammonia gas concentration measurement. Its signal conditioning circuitry ensures stable output, supporting direct connection to industrial control systems via its RS485 interface using the Modbus RTU protocol.

Engineered for durability, the sensor features a sealed, wall-mounted housing designed to withstand demanding conditions, including high humidity (15-90% RH) and wide temperature fluctuations. This makes it a dependable component for continuous, unattended monitoring in agricultural and industrial settings where ammonia leaks pose a safety or air quality risk.

Key Features

  • Industrial-grade electrochemical NH3 sensor with high repeatability (≤2%).
  • Flexible power input from 10V to 30V DC, suitable for diverse power rails.
  • Robust RS485 communication interface with Modbus protocol for system integration.
  • Waterproof (IP65-rated) enclosure designed for permanent wall-mounted installation.
  • Optional real-time display and environmental compensation via built-in T/RH sensor.
  • High-value build with a focus on long-term stability and minimal maintenance.
  • Configurable for multiple analog outputs (0-5V, 0-10V, 4-20mA) upon request.

Applications

  • Continuous ammonia concentration monitoring in livestock and poultry housing for animal welfare and ventilation control.
  • Safety leak detection in industrial settings such as chemical processing plants, fertilizer production, and refrigeration facilities.
  • Environmental monitoring at waste treatment plants, composting sites, and wastewater management facilities.
  • Air quality assessment in agricultural storage areas and laboratory fume hood exhaust analysis.
  • Integration into building automation systems (BAS) for smart farm and industrial facility management.

Frequently Asked Questions

What is the communication protocol for this ammonia sensor?

This sensor uses a standard RS485 interface with the Modbus RTU protocol. This allows for reliable, multi-drop communication over long distances, making it easy to integrate with industrial PLCs, SCADA systems, or data acquisition modules that support Modbus.

What is the power supply requirement for the RS-NH3 sensor?

The sensor operates on a wide-range DC power supply from 10V to 30V. This flexibility allows it to be powered by common industrial 12V or 24V DC power rails, as well as regulated laboratory power supplies, simplifying installation in various environments.

Is this sensor suitable for outdoor or high-humidity environments?

Yes, the sensor features a waterproof (typically IP65-rated) wall-mounted enclosure designed for industrial use. It can operate in environments with humidity ranging from 15% to 90% RH (non-condensing) and temperatures from -20°C to +50°C, making it suitable for barns, processing plants, and other harsh conditions.

Can the output be changed from RS485 to an analog signal?

The standard model ships with an RS485 Modbus output. However, Renke offers configurable versions supporting analog outputs such as 0-5V, 0-10V, or 4-20mA. You would need to specify this requirement at the time of ordering the specific variant.

How do I mount and install this ammonia gas sensor?

The sensor is designed for wall mounting. Its enclosure includes mounting holes for secure attachment. For accurate readings, install it in the target monitoring area, connect the provided wiring for power (10-30V DC) and the RS485 communication lines (A, B, GND), and ensure it is positioned away from direct air vents or excessive dust.
