| Can the sensor be run dry, i.e. on the gas side of an accumulator? |
|
| Yes, the sensor is designed to run either on the gas sided or the oil side of the accumulator. Consult factory for recommendations specific to gas or oil operation. |
| |
| Do oil vapors or other airborne contaminates affect the operation of the sensor? |
| Since the core sensor is a non-contacting technology, there are no concerns with regard to films or oxidation. |
| |
| What is the pressure rating of the enclosure? |
| The standard enclosure has a working pressure rating of 5,000 psi. |
| |
| What type of output does the sensor produce? |
| The sensor can be operated with any standard signal conditioner. Outputs of 0-5V, 0-10V, and 4-20mA are most common. Magnetostrictive-based sensors are available with virtually any output, including CAN Bus. |
| |
| How long can the flexible conduit be? |
| There is no practical length to the flexible conduit. However, consideration must be given to reduction in cable velocity due to drag; drag is significantly reduced if the sensor is installed on the fluid side. (Ref PN SL0390) |
| |
| How much can I bend the flexible conduit? |
| The bend guidelines for the Teflon-lined conduit are the same as standard SAE 100 R16 hydraulic hose, with a MBR of 3.5 inches. (Ref PN SL0390) |
| |
| Is there a wear or drag penalty for bending the flexible conduit? |
| In oil, no penalty; in gas (dry) applications, some reduction of cycle life should be expected with long runs and bends. Bending the conduit in dry (gas-side) installations will increase drag and wear of the conduit liner, but still yield a cycle life of 20,000 to 40,000 full cycles. Pre-lubricating the conduit can increase the cycle life. Straight conduit installations in dry environments have no drag or wear considerations. In high-cycle applications requiring long conduits with bends, it may be preferable to install on the oil side, where the conduit is continuously lubricated. (Ref PN SL0390) |
| |
| What are the cycle life limitations? |
| The core sensing technology is non-contacting, which has unlimited cycle life. All SL Series sensors have been tested to a minimum of 1 million full stroke cycles under various conditions, including dry installations. Mechanical components of the sensor are designed for multiple millions of full-stroke cycles |
| |
| Are dither cycles a problem? |
| Non-contacting LVDT is immune to dither wear. Extreme dither applications should be tested prior to field deployment. |
| |
| How fast does the cable recoil? |
| Our test facility has a maximum velocity of 80 inches/second, which, the sensor is capable of tracking. Factors which will affect cable speed include conduit length, conduit bends, fluid type and temperature. |
| |
| What if the oil surrounding the sensor is frozen solid? |
| Like most hydraulic system components, the CPI sensor will not operate in a solid medium. |
