Portable Sensor Display Strain Bridge InputPSDS-HSBK-A
SKU: PSDS-HSBK-A
Description
The PSDS is a modern, high-performance handheld display unit designed to replace the legacy PSD and TR150 ranges. It provides precise, reliable measurement display for strain bridge-based sensors such as load cells and pressure transducers, with sensitivity up to ±480 mV/V.
Ideal for both field and industrial use, the PSDS supports up to six user-defined calibration ranges—perfect for applications requiring multiple sensor types or loading modes (e.g., tension and compression). Each calibration range retains user preferences including selected units and tare values for quick, seamless switching.
TEDS (Transducer Electronic Data Sheet) compatibility allows automatic sensor recognition and calibration updates when using templates 33, 40, or 41, simplifying setup and reducing human error.
With up to six selectable display modes, the PSDS gives users full control over how measurements are presented, while the soft-key interface allows access to context-specific functions.
Configuration is easy: full setup is available via the free PC-based Toolkit (requires optional right-angle cable), while simple in-hand menu-driven configuration is also supported, including two-point calibration.
Powered by two internal non-rechargeable AA alkaline batteries, the PSDS is designed for flexible use—either handheld or mounted to equipment, dashboards, walls, or desks using optional mounting accessories.

FAQ
Our PSDS Help Centre pages can be found here
| Q | Is there a shunt cal function in the PSDS handheld? |
| A | Yes! This is accessed by using one of the display modes in the library. See here |
| Q | How can I have different resolution settings for different ranges in the PSDS? |
| A | In the PSDS we have decimal places and resolution set separately.
DP is set by the unit type, for example kgf. Every time kgf is selected the same amount of DP will be used. (As well as setting this in the toolkit, it is possible to do a long key press left/right to move these DP on the fly). Resolution (size of step) is set on a per range basis, in the base units of that range. For example, it would be possible to do the following: DP set to 0.000 for kgf Range 1: Set resolution to 0.001. 0.000-1.000 will be displayed in steps of 0.001 Range 2: Set resolution to 0.1. 0.000-10.100 will be displayed in steps of 0.100 Range 3: Set resolution to 1. 0.000-1000.000 will be displayed in steps of 1.000 (Available resolutions are 1, 2 and 5 and these are set in the base unit if you choose a different resolution, the nearest will be applied. So if you put in 0.3, the display would increment in steps of 0.2. Unit conversion is also applied to the resolution if you change units and it will snap to the nearest appropriate resolution.) Another consideration might be whether it would be more useful to show Range 1 as grams force, Range 2 as kilograms force and Range 3 as tonnes force metric? Then each of those could have the appropriate resolution and DP set? |
| Q | How many digits are in the displayed results screen of the PSDS? |
| A | Up to 7 digits plus the sign. See here for an example: |
| Q | PSDS not recognising additional TEDS tables |
| A | This could be down to the order of the tables and the presence of proprietary/unsupported ones.
Please note, the order of tables in the TEDS device is important. The order must be:
(When the PSDS detects a non-recognised table (such as a manufacturer defined one) it will stop reading the TEDS device. This means that if you have a proprietary/unsupported template before your template ID=40 table then the PSDS will never get that far.) |
| Q | How do I use different displays in my PSDS? |
| A | See Here |
| Q | My PSDS is showing strange readings, why? |
| A | If you are seeing maximum or minimum full scale, it is possible that you are in 6-wire measurement mode but only have four wires connected.
See the manual for wiring suggestions. |
| Q | How can I reset my PSDS to defaults? |
| A | If you have not set any passwords in the PSDS then you can load the following file into it using the save/restore feature in the toolkit. |
