Barometers
-
These barometers can be found in the section to measure absolute pressure, differential pressure in respect to the atmosphere and negative pressure. There are barometers such as the DB2 digital barometers that have an internal memory for up to 750 Barometers to measure absolute pressure, differential pressure in respect to the atmosphere and negative pressure. readings and an analogue output of 0 to 1 volts. These barometers are perfect to measure atmospheric pressure, also called barometric pressure, is an expression for the weight of air (atmosphere) due to the earth''s gravitational pull. This pressure at sea level is 1013.25 mbars (milibars).

Ultra-thin Mass Flow Controller
DZ-100
-
The DZ-100 inherits the same CRITERION™ technology—a differential pressure detection system for laminar viscous flow ranges—used on HORIBA STEC’s MFC, the D500. This innovative technology controls the mass flow of various gases with high precision. As with the D500, the user-configurable DZ-100 supports multi-range and multi-gas applications. The compact design of the MFC reduces the internal volume of the internal gas flow path, and the optimized control algorithm improves response characteristics. It uses a compact CPU with high processing capacity, and the piezo drive circuit and control CPU are installed in the MFC module while the power supply components are housed in a separate small control box. Up to four MFC modules can be controlled by connecting them with the dedicated miniature connectors.

Differential Pressure (Density)
VEGADIF
-
In density measurement of liquids with differential pressure, two pressure measuring points are mounted at a fixed distance from each other. There are thus two different pressures acting on the system. The differential pressure transducer calculates the density of the medium from the resulting pressure difference.

Pressure/ Vacuum Sensors
-
There are three different types of pressures that can be measured using Premier Electrosystems' Pressure Sensors: Gauge, Absolute, and Differential. Gauge pressure is the pressure measured relative to the ambient atmospheric pressure.A typical application for a gauge pressure sensor is to measure liquid levels in a vented tank using the difference in hydrostatic pressure and ambient atmospheric pressure. Absolute pressure sensors will give the result relative to zero (a perfect vacuum). This is useful in applications where there is a direct effect of altitude on the pressure being measured. Differential pressure sensors measure the difference in pressure between two points. Differential pressure sensors are often used to monitor airflow in HVAC applications.

Multivariable Transmitters
-
The Multivariable transmitter measures and calculates the mass flow as a function of differential pressure DP as well as absolute pressure and the temperature. Therefore it should be used whenever DP flow measurement needs a compensation of temperature and pressure. The main advantage is to have just one single device in the field instead of several transmitters and a mass flow calculator.
