Celesco DV301 · Combination Position + Velocity Sensor · potentiometer + DC tachometer · 2–100 in. stroke
The Celesco DV301 combines a precision potentiometer (position) with a DC tachometer (velocity) in one housing. It orders as DV301 – RRRR – A D F (range, cable tension, output impedance, connector). Example: DV301-0060-111 = 60-inch range, standard tension, 500 Ω pot, 6-pin plastic connector. Older 11-digit codes (e.g. DV301-0060-211-1110) decode the same way — extra digits are reserved positions.

Special Options & Notes
- The velocity output is a self-generating DC tachometer — no input voltage required; output voltage at 100 in./min depends on the range code (66–322 mV).
- Cable tension option 2 or 3 in legacy 11-digit codes reduces the velocity output signal by 50%.
- Codes with digits that don't match the tables above are factory specials or distributor stock numbers — contact us with the full code.
Frequently Asked Questions
What does DV301-0060-211-1110 mean?
A Celesco DV301 position + velocity transducer with 60-inch stroke (0060). In the legacy 11-digit code the following digits are reserved positions; the meaningful digits select the cable tension, the 500–10,000 Ω position potentiometer and the electrical connector. The official short form is DV301-0060-A-D-F (e.g. DV301-0060-1-1-1 = 60 in., standard tension, 500 Ω pot, 6-pin plastic connector).
Does the DV301 need a power supply for the velocity signal?
No. The velocity channel is a self-generating DC tachometer — it produces a voltage proportional to cable speed with no input voltage. Only the position potentiometer needs an excitation voltage (see the D order code for the max input rating).
What is the difference between the 1, H and M tension options?
They set how hard the measuring cable is pulled back. 1 = standard tension (±30%), H = high tension (±40%), M = max tension (±40%) — e.g. on a 2–20 in. range: 39 oz / 65 oz / 116 oz. Higher tension improves cable tautness at high acceleration but adds load on the application.
