Macro Sensors Gauge Tank Volume Changes
Configured with a float, Macro Sensors HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability, armature core of the LVDT. The 4 to 20-mA loop-powered LVDT position transmitter senses the position of the core and, therefore, the level of the float. Sensitivity to the change in level depends on the length of LVDT.
How to Calibrate an AC-operated LVDT Linear Position Sensor
Calibration is necessary before the installation of an AC- operated linear position sensor to ensure accuracy. Calibration corrects any slight variances between sensors, helping to improve repeatability. Because of the linearity of LVDT Sensor output, a simple two-point calibration is simple. Two points should be as far apart as possible, but within the linear range of the LVDT Linear Position Sensor and preferable within the measurement range in which it will be used. In applications where the LVDT is used on both sides of null…
Macro Sensors' New Subsea LVDT Measurement Devices
US-based Macro Sensors introduces a line of submersible LVDT Position Sensors for use as part of subsea measurement systems. Macro Sensors say that their LVDTs are proven to offer reliable measurement and feedback for continuous monitoring.
