DV-6S: The Ideal Vacuum Sensor for Truck, Rail and ISO Container Cryogenic Applications
In cryogenic applications, especially those mounted on trucks, railcars, and ISO containers, vessels face some of the harshest mechanical and environmental conditions in industry. Because these tanks are in motion, often over uneven terrain or long rail routes, the vacuum sensor must be reliable and remain accurate despite constant vibration. Vibration, shock, temperature swings, and outdoor exposure all place immense demands on sensors tasked with delivering reliable vacuum measurements.
Teledyne Hastings Instruments’ DV-6S Thermocouple Gauge Tube was purpose-built to thrive in these environments. Below is a deep dive into what makes the DV-6S uniquely suited for mobile cryogenic vessels.
Engineered for Extreme Ruggedness
The DV-6S isn’t just a more durable version of our DV-6R ruggedized vacuum gauge tube. It was specifically designed and tested
Teledyne Hastings Digital 300 Series: Did You Know?
Most common gas records are already available in the Digital 300 Series.
Teledyne's Digital 300 Series mass flow meters and controllers come equipped with 40+ commonly used gas records preloaded in memory, eliminating the need for manual setup.
These can be easily accessed from the optional front touchscreen display or via free user software – enabling quick, flexible operation and seamless switching from one gas to another.
The Digital 300 Series uses a thermal-based mass flow sensor. This sensor is designed to provide exceptional linear response to changing flow rates. In addition, the electronics associated with each sensor are precisely tuned to give fast response times. Teledyne configures and tests each individual valve to your flow rate, gas, and pressure
Most people are aware that the HVG-2020B wide range vacuum gauge has an optional display, but not everyone realizes that it's much more than just a display. It's actually a color touchscreen display and is packed with features. Let's take a look.
The HVG-2020B has 5 different display modes. Simply touch the icon on the lower left side to toggle through each one.
IP-67 Mass Flow Meters (MFM) and Mass Flow Controllers (MFC) for All Sizes
Teledyne Hastings Instruments introduced the IP-67 Enclosure Version for our high accuracy Digital 300 Series of thermal mass flow meters and flow controllers in 2018. The IP, or Ingress Protection rating, describes the instrument’s ability to operate in challenging environments. The first number, 6, indicates that the flow instrument has total protection against dust (particulate). That’s the highest-level of dust protection achievable under the IP Code. The second number, 7, refers to protection from liquids.
The Digital 300 Series with optional IP-67 enclosure can withstand water immersion up to one (1) meter for thirty (30) minutes. While it may not be obvious to everyone, it offers the liquid protection of the one meter / thirty-minute immersion as well as all lesser liquid codes (from dripping water through powerful water jets).
Teledyne Introduces the HVGPR Pirani Vacuum Gauge for Compact, Cost-Effective System Integration
IES is pleased to highlight a new product release from our partner, Teledyne Hastings Instruments: the HVGPR Pirani Vacuum Gauge. Designed with OEMs and system integrators in mind, the HVG(PR) delivers reliable Pirani performance in a compact, competitively priced package optimized for modern vacuum systems.
Proven Pirani Technology with Integrated Electronics
The HVGPR is a thermal-based Pirani vacuum gauge with integrated electronics, using the same proven Pirani sensor found in the HVG-2020B. This precision-welded hot-wire sensor design has been in high-volume production since 2019, providing a strong

Thermal mass flow measurement instruments are typically separated into two main categories: Mass Flow Meters and Mass Flow Controllers. It’s estimated that over 90% of mass flow measurement instruments sold are mass flow controllers. So, it’s no surprise that most mass flow application conversations focus on mass flow controllers. Notwithstanding, there are still numerous applications for which mass flow meters are critical.
The following are common applications for mass flow meters (also known as thermal mass flow meters):
HVG-2020B: Choosing the Right Analog Output Signal for You
The HVG-2020B wide range, dual sensor vacuum gauge takes measurement to the next level. With a Piezo based sensor and a thermal based Pirani sensor, it accurately and confidently measures pressures across seven decades. The Piezo sensor is media isolated, gas composition independent, and periodically zeroed by the Pirani sensor. An ambient thermal sensor enables the instrument to adjust for temperature and therefore better accuracy.
The HVG-2020B offers multiple linear and logarithmic analog output signal options.
Why do you think Teledyne offers so many logarithmic output options?
The linear output may not always be useful. Remember: the HVG-2020B is a wide range gauge that covers seven (7) decades of vacuum. That’s a huge range to cover with a linear output signal!
For example, if you are using 0 – 10 VDC Linear Output:
Wide range vacuum gauges are measurement instruments that use a combination of technologies to cover from atmosphere to ultra-high vacuum. Examples of these technologies include a Pirani gauge, piezo sensors, or hot and cold cathodes. A wide range gauge would use 2-3 of these technologies that couldn’t be covered by just one of them alone.
As an example, Pirani vacuum gauges measure a low to medium range vacuum and can be paired with either a piezo gauge or an ionization gauge to measure either atmospheric pressure or ultra-high vacuum depending on the purpose of the wide range gauge. This helps provide a compact solution to your vacuum application by providing a single port pressure
The Importance of Specifying Gas Flow Range on a Mass Flow Controller
The Full Scale (FS) Range and Gas on a Mass Flow Controller (MFC) directly correlates to the transmitted output (analog or digital) of the device. In an analog device, the maximum output value (such as 5 vdc or 20 mA) will be equivalent to the FS value. The accuracy of most MFCs is a function of this FS Range.
