Aecl AHT-5 Series Temperature & Humidity Transmitter | DLK Vietnam

The Aecl AHT-5 Series temperature & humidity transmitter features advanced CMOSens technology for high accuracy, rapid response (< 10 seconds), and exceptional long-term stability. It supports versatile mounting options (wall, duct, outside air, separated probe) with flexible signal outputs including 4-20mA, 0-10V, RS485 Modbus, or wireless long-range LoRa.

Breakthrough Environment Monitoring Technology With Aecl AHT-5 Series Transmitters

In the era of smart building automation and industrial process optimization, microclimate monitoring requires measuring instruments with absolute accuracy, rapid response time, and robust long-term reliability. Perfectly matching these strict technical standards, the Aecl AHT-5 Series Temperature & Humidity Transmitter has established itself as a leading environmental monitoring solution globally. Equipped with advanced microprocessor technology and highly adaptable communications, this series delivers exceptional dependability for modern energy management and HVAC control systems.

Core Technological Foundation and Operating Principle

The technical excellence of the Aecl AHT-5 Series lies in its integration of advanced CMOSens technology. This state-of-the-art method combines the sensing elements and the analog/digital signal processing circuits onto a monolithic CMOS silicon chip. When environmental conditions change, the high-quality polymer capacitive humidity sensor and wide-range temperature sensor capture the physical variations. The embedded microprocessor then executes instantaneous digital linearization and precise calibration.

This intelligent processor architecture ensures a compact footprint, outstanding power efficiency, and superb immunity against industrial electromagnetic interference (EMI). The processed signals are immediately transmitted through standard industrial outputs, enabling building management systems (BMS) and programmable logic controllers (PLCs) to gather smooth, lag-free real-time environmental data.

Optimizing Operational Efficiency Across Major Industrial Applications

With multiple structural and mounting configurations, the Aecl AHT-5 Series temperature and humidity sensor provides comprehensive field solutions for distinct industrial environments:

• Intelligent Building Management Systems & HVAC Automation: Tailored for commercial malls, institutional spaces, and multi-story corporate towers, the wall-mount type features a sleek, aesthetic design that blends naturally into modern architecture. It continuously delivers environmental microclimate parameters to the central BMS, maximizing the operational efficiency of AHUs and Chillers to maintain high indoor air quality while reducing overall power utility costs.

• Pharmaceuticals & Critical Hospital Cleanrooms: Critical clinical and laboratory settings demand absolute bio-contamination control and tight humidity tolerances. The separated model (featuring an external sensing probe extended by a 3,360 mm cable) allows engineers to mount the main LCD control enclosure outside for direct monitoring, while the IP65-rated probe operates deep inside isolated zones without compromising room sterility.

• Ventilation Ducts & Industrial Process Airflow: For heavy-duty industrial process pipelines and supply ducts, the duct-mount model equipped with a 300mm length and Ø15mm diameter probe is the standard choice. It penetrates directly into the air streams to continuously evaluate moving air mass quality, delivering vital statistics for fresh air intake or factory process exhaust control.

• High-Tech Agriculture & Dusty High-Static Industrial Environments: In agricultural greenhouses, intensive livestock enclosures, or textile manufacturing plants characterized by saturated moisture and static-inducing cotton dust, the dedicated outside air configuration offers maximum resilience. Engineered with a rugged IP65 waterproof and dustproof housing, combined with high-grade protective filter caps, it ensures long-term operational continuity under severe outdoor weathering or continuous condensing states.

Unrivaled Value and Engineering Advantages :

Deploying the Aecl AHT-5 Series provides significant economic and technical advantages for mechanical contractors and building developers alike:

•  An ultra-rapid response speed of under 10 seconds (measured within 20% to 80% RH range) allows control loops to trigger immediate mechanical corrections, eliminating localized overheating or destructive thermal shocks.

•  Superior long-term stability with minimal drift parameters (< 0.03°C/year for temperature and < 0.25%RH/year for humidity) guarantees stable multi-year performance without requiring frequent field recalibrations, minimizing technical field maintenance costs.

•  Smart switchable connectivity between traditional wired RS485 (Modbus RTU) protocol and advanced wireless long-range LoRa technology (Peer-to-Peer, operating across 862 ~ 932 MHz bands). This innovation simplifies cable topologies, trimming up to 70% of engineering labor and wiring infrastructure costs in expansive industrial warehouses or historic building retrofits.

•  Enclosures are manufactured from top-tier fireproof ABS resin, adding an extra layer of intrinsic safety to industrial electrical sub-panels and plant control stations during sudden overcurrent situations.

Technical Specifications

Technical Ordering Nomenclature Guide

To facilitate streamlined project specification and accurate product ordering, engineers can format exact part numbers utilizing the manufacturer's standardized configuration matrix: AHT-[Code 1][Code 2][Code 3]-[Code 4][Code 5]M:

• Code 1 – Functional Parameters: 501 (Temperature only); 502 (Humidity only); 503 (Combined Temperature & Humidity); 504 (Humidity & Dew Point); 505 (Temperature & Dew Point); 506 (Temperature & Enthalpy); 507 (Temperature & Wet-bulb temperature).

• Code 2 – Mounting Configuration: W (Wall-mount); D (Duct-mount); V (Outside air); S (Separated remote probe type).

• Code 3 – Output Signal Interface: A (Linear analog 4-20mA current loop); 2 (Selectable voltage 0-10V/0-5V/1-5V); 4 (Serial RS485 Modbus RTU link); 6 (Dual integrated RS485 and wireless LoRa platform).

• Code 4 – Visual Display Option: X (Blind unit without local screen); D (Integrated LCD display for local real-time monitoring).

• Code 5 – Metrological Accuracy Tier: A (High-accuracy specification); B (Standard/Low-accuracy specification).

Practical Ordering Case Example: By selecting the configuration code AHT-503-WM-DA, the client receives a combined temperature and humidity transmitter manufactured by Aecl, engineered for wall-mount indoor installation, utilizing an analog 4-20mA current output, integrated with a local LCD visual screen, and built to high-accuracy parameters (Temperature accuracy of ±0.2°C and Humidity accuracy of ±2%RH under reference conditions of 25°C / 55%RH).
