TDC1000-GAS is an Ultrasonic Sensing Gas Flow Evaluation Module

This post sponsored by Texas Instruments.

The TDC1000-GASEVM is an evaluation module (EVM) that allows users to evaluate the operation and performance of the TDC1000 ultrasonic analog-front-end with TDC7200 time-to-digital converter for gas flow meter applications.

The kit comes with two evaluation boards: one has the TDC1000 (ultrasonic AFE), TDC7200 (time-to-digital converter), and MSP430 on-board. The purpose of this board is to excite the transducers, receive the returned echo, generate the STOP pulses, and digitize the time-of-flight to the MSP430 for further processing. This main board connects with a separate TDC1000-BSTEVM board (referred to as HV board for the remainder of this document). The purpose of the HV board is to boost the transmit pulses from 3.7V-to-30V to get a better received echo for applications where a higher range is necessary or when the ultrasonic medium is a gas or is exposed to vibration. The kit allows for two ultrasonic transducer connections and two RTD connections for temperature measurements. It uses the on-board MSP430F5528 to process data and a user-friendly GUI interface to display the data.

TDC1000-GAS is USB powered.
