Description

Control pressure variations better with Gefran’s K Series melt pressure transducers. The K Series uses a near-incompressible sodium potassium (NaK) to transmit pressure, integrates industry-leading strain sensing technology, and can be reliably used in high-temperature plastics processing applications (up to 1,000 degrees Fahrenheit/538 degrees Celsius).

Models:

  • K30
  • K31
  • K32
  • K33
  • KE0
  • KE1
  • KE2
  • KE3
0/5 (0 Reviews)
  • Exceptional Pressure Range: The K Series can read up to 1000 Bar/15000 PSI
  • AutoZero Function: The K-Series has an integrated AutoZero function that periodically recalibrates the baseline to prevent zero point drift and only activates when there is no pressure in the system. (KE models only)
  • Customizable Design: These transducers can feature diaphragms made of Inconel 718, 15-5 PH stainless steel, 17-7 PH stainless steel, or Hastelloy C276, depending on the temperature requirements. All diaphragms feature GTP coating for improved corrosion, abrasion, and temperature resistance.
  • NaK-Filled: All models are filled with sodium potassium to ensure stability.
We know how critical precision is in plastics processing. That’s why our product specialists at Hi-Watt are committed to helping you find the best solution. If you’re not sure which K Series sensor you need, our team will discuss application requirements with you to determine which model would offer better performance. After you purchase a sensor from us, you’ll continue to receive ongoing technical support to ensure you’re getting the most out of your sensor.
