Temperature Measurements with the Spider-80Ti using RTD Sensors

The Spider-80Ti is a front-end from the Spider-80Xi hardware platform that enables temperature measurement. Spider-80Ti supports temperature measurements from thermocouples and RTD (resistance temperature detector) sensors.

Each Spider-80Ti front-end adds 16 temperature measurement channels to the Spider-80Xi system. A Spider-80Ti front-end is user configurable to support either a PT100 RTD sensor or a K-type thermocouple. A combination of RTDs and thermocouples within the same Spider system is achieved by combining front-ends configured as RTDs and thermocouples.

This blog is part one of a two-part series. The next blog will discuss in detail about temperature measurements with the Spider-80Ti using thermocouples.

Load Cell Support and Ratiometric Sensors

A new and powerful addition to Crystal Instruments EDM software is enhanced support for load cells and other ratiometric sensors. The sensitivities of these sensors are dependent on the supplied excitation voltage, so it is crucial to provide precise excitation. Crystal Instruments’ latest software release of EDM 9.0 provides an effortless process to configure and setup load cells and other ratiometric sensors.

Strain Gage Connections

When designing and testing materials and products it is essential to understand its material properties and how it reacts to the forces and loads applied to it. The deformation a DUT experiences when a force is applied is called strain. Strain is the ratio of the change in length of a material to the original length. Strain can be positive (tensile) or negative (compressive).

Vibration Control Using Strain Gages: New Strain Rate Feedback

Crystal Instruments is excited to announce the addition of Strain Rate feedback to its arsenal of non-acceleration vibrational control strategies. The Spider-80SG/SGi system now supports the use of strain gauges as the primary control transducers. This feature allows users to define test profiles as a function of strain and frequency.
