Thermocouple Vacuum Gauge Tubes for Medium Vacuum
DV-6 Series
-
Teledyne Hastings, manufacturer of the original DV-4, DV-5, and DV-6 thermocouple vacuum gauge tubes, produces vacuum measurement equipment with exceptional stability, accuracy, and reliability under the most demanding conditions.The Teledyne Hastings’ DV-6 series thermocouple vacuum gauge tube acts as a localized sensor which is then paired with a selection of meters or controllers to provide reliable, cost-effective measurements in diverse applications. The robust sensor gauge tube is easily installed into vacuum systems and when properly excited, generates a thermoelectric voltage to provide a vacuum pressure measurement based on gas density. The DV-6 thermocouple vacuum gauge tube fully compensates for temperature and rate of temperature change.Thermocouple gauge tubes are calibrated on vacuum systems that contain N2 or Air, but can be used with other gases. Additionally, thermocouple gauges and their controllers can be recalibrated when a replacement thermocouple gauge tube is installed, following instructions in the manual. However, our DB-20 reference tube is available to confirm meter/controller performance. A complete line of installation accessories are also available to simplify the integration of our thermocouple gauge tubes into a variety of vacuum systems. Our goal is to provide “one less thing to worry about”, when performance matters! With a wide range of meter, fitting, relay and output options, the DV-6 series provides a reliable pressure measurement in numerous industries and applications.

60 GHz WR-15 Waveguide Tx Module
PEM010
-
The PEM010 is a highly integrated millimeter wave transmitter that covers the 60 GHz global unlicensed spectrum allocations packaged in a standard waveguide module. Transmitter architecture is a double conversion, sliding IF with wide bandwidth capability through the up-conversion chain from baseband to carrier. The I/Q interface accepts analog baseband signals which provides for flexibility in design and applications. The baseband input optionally supports FSK/MSK modulation for non-coherent applications. The transmitter incorporates a complete waveguide interface with low-loss transition between the chip and the WR15 waveguide port. The integrated package is small and lightweight, with a simple to use multi-pin ST4 connector for power, reference clock, digital control port and baseband signals. Either of two reference clocks can be used for setting 540 MHz or 500 MHz channel spacing.
