Druck PACE Tallis Pressure Indicator Module
PACE Tallis is the transfer standard, designed with market leading precision and long-term stability using Druck‘s TERPS resonating silicon technology. Designed for test bench, bench top and panel mount calibration, test and monitoring applications, PACE Tallis is a compact and robust transfer standard calibrator that is ideal for in-situ testing and interlaboratory comparisons.
Engineered to be a versatile offering, PACE Tallis maintains performance across a wide range of environmental conditions and test media to offer precision down to 10 ppm FS. The portability of PACE Tallis means remote, sub-optimal locations are now accessible for calibration with reduced risk of damage during transport due to the robust build of the unit.
With easy set up and operation, PACE Tallis provides a low cost of ownership Transfer Standard compared to deadweight testers. It is ideal for calibration labs, boasting long-term stability up to 15 ppm FS/year with minimal servicing required.
This PACE precision pressure indicator brings together the latest measurement technology from Druck to offer an elegant, flexible and economical solution to pressure measurement for test, calibration and monitoring.
By utilising Drucks‘ TERPS resonant silicon sensor technology, which exhibits market leading metrological characteristics, with specific regard to precision and long term stability, PACE Tallis provides versatility whilst maintaining performance in a wide range of environmental conditions and test media.
This versatility along with the configurability of 1, 2 or 3 reference sensors from 200kPa to 21.1 MPa enables PACE Tallis to fit a wide range of applications.
Druck has been at the forefront of pressure measurement technology for almost 50 years and still continues to push the boundaries of what is possible in terms of precision, stability and expanded uncertainty for a pressure transducer. The PACE Tallis is a compact, robust transfer standard, ideal for in-situ testing and interlaboratory comparison.

Tallis Performance Benefits
- Lower risk of errors during use (automated software vs user error)
- No effects of physical quantities to impact error budget (e.g. local gravity/ density of the media)
- Easy setup and operation
- Calibrated across a wide temperature range
- Guaranteed uncertainty budget (e.g. no induced errors due to poor piston cleanliness)
- Lower overall cost of ownership
- Lower product cost than a typical DWT
- Minimal servicing required (no cleaning of pistons etc)
- Automated software vs experienced and well-trained manual operators
- Reduced shipping costs for calibration
- Less "real estate" required for physical product.
- No need for expensive vacuum pumps, custom test benches
Druck PACE Tallis Tests and Applications
Druck PACE Tallis Leak test
Leak Test measures leak rate over the measure dwell time. At the start of the test, the instrument measures the applied test pressure of the user system. The instrument records the pressure change during measure dwell time. On completion the display shows the leak rate results, with leak rate per second or per minute in the current pressure units selected.
Switch test - standard with the analogue output or voltage free contacts option
Switch Test automates the testing of pressure switch devices. Following the test, displayed is the pressure at which contacts open and close and the switch hysteresis. Switch Test task can also be set to capture switch toggle max, min and average values.
Druck PACE Tallis Analogue output
The Analogue Output can be programmed via the setup menu screen to output a signal proportional to the instrument range selected. This allows the instrument to interface with PC or PLC I/O cards, remote displays, chart recorders or other data logging equipment.
Users can select outputs of 0 to 10 V, 0 to 5 V, -5 to 5 V and 0/4 to 20 mA. Precision with respect to host instrument measured pressure 0.05% FS over the host instrument operating temperature range, variable update rate to 80 readings per second. The option is programmable between minimum and FS pressure for proportional output against pressure.
Volt free contacts
Volt Free Contacts enable control of peripheral devices such as vacuum pumps, ovens, etc. Each VFC option has three independent volt-free NO/NC relay contacts. A number of conditions can be set within a PACE Tallis instrument to trigger a relay toggling its contacts.
