Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.

Shunt Voltage References
-
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

-
The Impulse Current Measuring Shunts ICMS are new designed tubular shunt types with best response behavior to match the high performance of the TR-AS digital recorder for comparative current measurements. A 1st partial response time less than 10ns and a settling times less than 20ns show the advantage of these shunts. They show no initial overshoot peak, no oscillations and do not need compensation box to optimize the transient behavior as known from e.g. cage shunts.

Turbine Flowmeters
-
Titan’s small turbine flowmeter range use a radial flow principle based on the Pelton wheel technique. This well proven method is the ideal way of measuring low rates of flow of low viscosity liquids. For these mini flowmeters, a jet of fluid is directed at a turbine that is mounted on robust low friction sapphire bearings. The geometry of the turbine and the fluid chamber ensures that the rotational speed of the rotor is proportional to the flow rate through the device. The use of this radial arrangement allows more energy to be imparted into the turbine, so the bearing drag is far less important. Furthermore, because more energy is available the bearings themselves can be a lot stronger so increasing the life of the flowmeter. For larger flows, some of the liquid can bypass the turbine chamber, which then behaves as a “shunt” to the metered fluid. Accuracy is still maintained and the output remains linear.
