Temperature Module with Signal Conditioner - 183145

Product Info
Accessories

This circuit supplies the sensing current and signal conditioning needed to use a fine wire sensor as a resistance thermometer. While the built-in thermocouple circuit is adequate to compensate for normal variations in tunnel temperatures, if higher frequency temperature variations are present, a faster sensor is required. It is for such applications that the Model 183145 is used.

The frequency attainable depends directly on the diameter of the sensor selected. For example, the 3 dB point for a 4 micrometer tungsten wire is about 700 Hz at 10 m/s. The maximum frequency increases with higher velocities or smaller diameter wires.

A wide range of computer-controlled current settings, low pass filters, gain settings, and offsets are provided to optimize the system for the sensor and the flow conditions. The temperature module plugs into a standard anemometer slow in the IFA 300 Research Constant Temperature Anemometer.

Thermal Anemometry Traverses

Computer-controlled traverses precisely locate and move a thermal anemometer probe as part of a thermal anemometer system. More Information

Cylindrical, dual sensor, cross flow - Probes

Sensors mounted 90° to each other and in a plane 90° to probe axis. For measuring two velocity components, correlations, and flow vectors in two-dimensional flows. Available in hot wire and hot film versions for gases (up to 150°C) and hot film version for liquids.

Cylindrical, single sensor, cross flow - Probes

Single sensor probes are used to measure one component of velocity. The sensor needles are designed to have minimum probe interference to measure cross flows.These probes are available in different sizes and configurations.

Cylindrical, triple sensor, cross flow - Probes

Standard probe for three-component measurements. Sensor orientation designed to minimize sampling volume and minimize flow disturbance. For velocity and turbulence measurements to 150°C. Available in hot film versions for gases.

Cylindrical, dual sensor, end flow - Probes

Sensors mounted 90° to each other and 45° to probe axis. Ideal for two-component velocity and turbulence measurements while providing minimum flow disturbance. Available in hot wire and hot film versions for gases (up to 150°C) and liquids.

Cylindrical, single sensor, end flow - Probes

Inexpensive, disposable probe for single component measurements up to 60°C. Sold in multiples of six probes. Available in hot film version for gases.

Cylindrical, triple sensor, end flow - Probes

Standard probe for three-component measurements. Sensors oriented to minimize sampling volume and flow disturbance. For velocity and turbulence measurements to 150°C. Available in hot film version for gases.

Supports and Adapters - Single Sensor Probe

Most TSI Thermal Anemometry probes are built with a plug-in connector. Thus, they require a probe support which serves to support the probe and provide an electrical connection to the anemometer. TSI probe supports come in a wide variety of configurations and lengths, for both single- and dual-sensor probes (standard three-sensor probes are designed with a probe support built-in), and for either gas or liquid flows. Right angle adapters, available for both single- and dual-sensor probes, allow probe mounting in an end flow orientation, even when the probe support is mounted in a cross flow arrangement. Totally immersible probe supports are also available for liquid applications.
