Story
Solutions for Environmental Monitoring

Application

Environmental Monitoring

We provide accurate and rugged instruments for monitoring natural waters or managing water processes with sensors for measuring pressure, temperature, vibration and water level.

TE Connectivity (TE) is a global technology leader, providing connectivity and sensor solutions essential in today’s increasingly connected world. TE provides sensors for water-resources monitoring market with long standing industry experience in the design and manufacture of water level sensors and systems. Our experience in media isolated pressure sensors provides our customers with unique advantages in creative product development and consistent product performance. KPSI and TruBlue water-level transducers are available in custom ranges and a wide choice of accuracies, materials, and cabling. With your choice of analog or digital output, our sensors are easily adapted to most data systems. Or, use self-powered units with on-board memory for remote monitoring or long term deployment.
