This advanced state-of-the-art device can reduce the number of wire pairs needed to monitor pressure and flow
transducers by over 90%.
Each TTX-2 logic unit can have from 1-5 transducers attached, resulting in only one pair of wires for 250 transducers. Systems can be
branched in any direction, reducing the need for wire pairs, while obtaining accurate readings at distances up to 100 miles.
Reliable, low voltage digital signaling with six levels of logic ensures accuracy and long component life.
- Reduce wire pair requirements by over 90%
- Requires only one pair of wires for up to 250 transducers.
- Accurate readings at distances of up to 100 miles.
- Available in three different models of up to 5 transducers per housing.
- Utilizes standard "F" cup.
- Also available for flow monitoring
The number of logic units per loop range from 1-127, depending upon loop resistance and placement of logic units on the pair. Logic units are available in 2 bank and 5 bank housings.The
body and manifold are tin-plated brass.
TYPICAL PLACEMENT OF TTX-2 LOGIC UNITS*
Loop
length | Wire
gauge | No.Logic
Units | Max.No.
Transducers** | Interval |
|---|
| 100 mile (160km) | 19 AWG | 32 | 250 | 16,500' (5029m) |
| 50 mile (80km) | 19 AWG | 74 | 250 | 3,570' (1088m) |
| 10 mile (16km) | 26 AWG | 70 | 250 | 750' (229m) |
*Example shown is for single loops. Branches and "Y's" will increase the number of logic units on a total loop.
**Each Logic Unit may have from 1-10 transducers attached.
