KD NaK filled Melt pressure transmitters
Features
- The KD Series are for use in high temperature applications where the process temperatures may reach 538°C(1000°F) such as high temperature engineered polymers.
- The K Series utilizes standard melt pressure principles and construction, but uses a near incompressible NAK(Sodium Potassium) for pressure transmission.
- The K Series strain sensing technology is bonded foil strain gage.
- Electrical
- Digital output signal with DP404 CAN OPEN communication protocol
- Transmission frequency (Baud rate): 10 Kbaud to 1 Mbaud (default 500 Kbaud)
- Software / Hardware selection of Baud rate and ID nodes
- Operation with 1 or 2 settable alarm limits
- “Autozero” for temperature compensation
- Zero and span drift compensation
- 80% FSO calibration signal
- Mechanical
- Pressure ranges: 0-35 to 0-700 bar / 0-500 to 0-10000 psi
