Fluke 2635A Hydra Portable Data Acquisition Module Description

Functions

Performs multi-channel, high-resolution analog-to-digital conversion of diverse physical parameters including voltage, current, resistance, temperature (thermocouple/RTD), and strain. Incorporates signal conditioning, linearization, and cold junction compensation. Executes programmed scan intervals for time-stamped data logging to internal memory or real-time output via serial or Ethernet interfaces for subsequent analysis and monitoring.

Platforms

The device functions as a portable data acquisition module, capable of measuring voltage, current, temperature, and resistance with high accuracy. Its hardware platform incorporates a microcontroller unit (MCU) for data processing, analog-to-digital converters (ADCs) for signal conversion, and communication interfaces such as RS-232 and GPIB. It interfaces with sensors via screw terminals or optional terminal blocks and connects to PCs or data loggers for data transfer and analysis. Common applications are process monitoring, environmental studies, and general-purpose data logging.

Applications

Versatile benchtop/portable data logger supporting 20 analog input channels plus 8 digital I/O for multi-point temperature, voltage, resistance, and frequency measurements. Accepts direct connection of thermocouples (J, K, T, E, R, S, N, B types), RTDs, thermistors, and DC/AC voltage signals up to 300V. Features isolated universal inputs, built-in cold junction compensation, and 0.1°C temperature resolution. Interfaces via RS-232 for PC communication and includes internal memory for standalone logging. Commonly deployed for thermal profiling, environmental monitoring, product validation testing, HVAC system commissioning, industrial process monitoring, quality control documentation, and research data collection requiring simultaneous multi-channel measurements with timestamp recording.

Accessories

Standalone unit. Interfaces include a 9-pin D-subminiature female RS-232 port for PC communication, an 8-position screw terminal block for 4 TTL alarm outputs and 4 TTL digital inputs, and an IEC 320-C14 AC power inlet. A 2635A-101 Universal Input Module with 44 screw terminals is required for connecting up to 20 universal analog channels. Associated equipment includes a PC for control via Hydra Logger software. Optional accessories include a 2635A-702 soft carrying case and thermocouple wire kits.

Interfaces

RS-232 DB9 male connector, IEEE-488 connector, digital I/O, analog input screw terminal, ac power inlet

Specifications

A data acquisition unit designed for multi-point temperature and low-voltage measurement applications, featuring 20/21 analog input channels, universal input module compatibility, and selectable measurement rates up to 250 channels per second. Equipped with RS-232 and IEEE-488 interfaces for remote operation, the unit supports thermocouple, RTD, thermistor, DC voltage, DC current, and resistance measurements. Incorporates high-resolution scanning with 16-bit ADC technology, built-in math and statistical functions, and flexible triggering options. Ideal for environmental testing, process monitoring, R&D experimentation, and quality assurance applications requiring accurate multi-channel data collection with PC connectivity.
