Frequently Asked Questions
What temperatures can the KD-1950 operate in?
The KD-1950 operates from -320°F to +1000°F continuously, and up to +1200°F short term. It is calibrated for either the cryogenic range (-320°F to +77°F) or the high-temperature range (+77°F to +1000°F).
What pressure can the KD-1950 withstand?
The KD-1950 is rated to 3500 psi. For applications above 3500 psi, the KD-1925 is rated to 5000 psi.
What is the difference between the KD-1950 and KD-1950M?
The KD-1950M is designed for magnetic targets and has a measuring range of 0.100 inch (2.54 mm). The standard KD-1950 has a measuring range of 0.150 inch (3.81 mm).
What electronics does the KD-1950 use?
The KD-1950 uses KDM-8206 signal conditioning electronics, available in single-channel and multi-channel rack-mountable configurations.
What applications is the KD-1950 used for?
Typical applications include nuclear reactors, steam and gas turbines, turbine and rocket engines, chemical processes, research projects, and high-temperature processing.
How does the KD-1950 compare to the KD-1925 and KD-1975?
The KD-1950 offers a 0.150 inch measuring range, between the KD-1925 (0.050 inch) and the KD-1975 (0.200 inch). The KD-1925 has the highest pressure rating at 5000 psi, while the KD-1950 and KD-1975 are rated to 3500 psi.
