Titan TPT-SDI Product Highlights
The Titan TPT-SDI Digital Pressure Transmitter is a purpose-built solution for engineers who need reliable digital pressure measurement with minimal power overhead. Covering a wide measurement window from 0.5 bar up to 600 bar, with accuracy classes of ≤±0.25% and ≤±0.10% FS, the TPT-SDI delivers laboratory-grade precision in a sensor designed for field deployment. The ceramic piezo-resistive element offers outstanding corrosion resistance, making it well-suited to harsh media, outdoor enclosures, and chemically aggressive environments.
What sets the TPT-SDI apart is its native SDI-12 v1.4 digital interface. Unlike traditional 4–20mA or voltage-output transmitters, SDI-12 enables multiple sensors to share a single bus, dramatically simplifying wiring on remote sites. With a current consumption of under 250µA in idle and under 4mA when active, the TPT-SDI is purpose-built for battery-powered data loggers, solar telemetry stations, and remote terminal units (RTUs) where every microamp counts. Integrated lightning protection (gas discharge tube), wide temperature range, and ≤±0.10% FS long-term stability ensure the sensor performs reliably year after year in unattended installations.
SDI-12 Pressure Transmitter Applications
The Titan TPT-SDI is widely deployed in environmental and hydrological monitoring, where its SDI-12 output integrates seamlessly with industry-standard data loggers from manufacturers used across the water industry. Hydrologists and environmental agencies use it for surface water level, groundwater, and borehole monitoring, where low power draw allows long-term unattended operation on small solar panels or battery packs.
In remote telemetry and RTU installations, the TPT-SDI’s digital output eliminates analogue signal degradation over long cable runs. Network operators in water utilities, irrigation schemes, and pipeline monitoring benefit from the ability to daisy-chain multiple SDI-12 sensors on a single cable, reducing both installation cost and field maintenance time.
For fire hydrant and water network monitoring, the TPT-SDI’s robust ceramic sensor and IP67 sealing make it ideal for direct mains pressure measurement. Water companies use it to detect leaks, monitor distribution pressure, and validate hydrant flow performance — all powered from compact battery packs over multi-year deployment cycles.
The TPT-SDI is equally at home in OEM installations, where system integrators embed it into pressure monitoring products, portable test kits, and smart infrastructure devices. Its standardised SDI-12 interface and configurable part-numbering system make it straightforward to specify and integrate.
In laboratory and academic research, the TPT-SDI provides researchers with a stable, digitally calibrated pressure reference. Combined with the optional USB-SDI12-PRO interface adaptor and configuration software, the sensor can be quickly configured, polled, and logged from any PC — making it well-suited to research, teaching, and instrument development.
Finally, the TPT-SDI is widely used with third-party SDI-12 data loggers for long-duration studies in hydrology, agriculture, geotechnical monitoring, and environmental science, where data integrity and minimal power consumption are essential to mission success.
