Hypertherm 128659 Pressure Transducer

Product Description

The Hypertherm 128659 Pressure Transducer is a replacement part for the PowerMax 1650 plasma cutting system. This transducer is responsible for measuring the pressure of the plasma gas and ensuring that it is within the proper range for cutting. If the pressure is too low, the plasma arc will not be able to form properly and the cut quality will suffer. If the pressure is too high, the plasma arc will become unstable and the cut quality will also suffer.

The 128659 Pressure Transducer is a critical component of the PowerMax 1650 plasma cutting system. It is important to ensure that this transducer is properly installed and calibrated in order to maintain the best possible cut quality.

Installation

The 128659 Pressure Transducer is installed in the plasma cutting torch. The transducer is connected to the plasma gas supply line and the output signal is connected to the control board. The transducer should be installed in a location that is protected from shock and vibration.

Calibration

The 128659 Pressure Transducer is calibrated at the factory. However, it may be necessary to recalibrate the transducer if it is damaged or if the cut quality begins to suffer. The transducer can be calibrated using a pressure calibrator.

Troubleshooting

If the plasma cutting system is not cutting properly, the 128659 Pressure Transducer may be the cause. Check the following:

• Check the input pressure range. The input pressure range of the transducer is 0-100 PSI. If the input pressure is outside of this range, the transducer will not be able to measure the pressure correctly.
• Check the output signal. The output signal of the transducer should be 0-5 VDC. If the output signal is not within this range, the transducer may be damaged.
• Check the accuracy, repeatability, and hysteresis. The accuracy, repeatability, and hysteresis of the transducer should be within the specified limits. If any of these specifications are not met, the transducer may need to be calibrated.

If you have checked all of the above and the transducer is still not working properly, you may need to replace it.
