Pressure Sensors
A pressure sensor is a device that senses pressure and converts it into an electric signal where the amount depends upon the pressure applied. TE Connectivity (TE) designs and manufactures pressure sensors ranging from the sensing element to system packaging for harsh environments. We are an industry leader for our range of both standard and custom pressure sensors, from board level components to fully amplified and packaged transducers. Based on piezoresistive Micro-electromechanical systems (MEMS) and silicon strain gauge (Microfused, Krystal Bond) technology, our sensors measure everything from less than one inch of water column (<1.25 mbar) to 100K psi (7K bar).

Pressure Comparator (System D)
P Series
AMETEK Sensors, Test & Calibration
The P-Series (System D) comparators are hydraulic screw pumps designed for easy, controlled, high pressure generation. Each comparator includes a 4 connection manifold, which can be used for the reference indicator, the device under test, a fine adjust, an isolation valve, or a fluid reservoir. The adjustable reference pressure port lets you set your reference gauge at the best viewing angle. Three models are available for hydraulic oil, water, or both.

Differential Interferometer
10715A
The Keysight 10715A Differential Interferometer performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long term stability. The 10715A minimizes dead path, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The resolution of the measurement is twice that of a linear or single-beam interferometer.

Pressure Measurement Film
Prescale
Prescale allows you to easily measure pressure balance, distribution, and size. Created using Fujifilm's advanced thin film coating technologies, the pressure inspection sensor on the entirety of the film allows you to confirm pressure distribution of the entire surface at a glance. The color appears red where pressure is applied, and the color density varies according to the amount of pressure. To cover a wide pressure range (0.006 to 300 MPa), we supply eight types and nine variations of Prescale.

Differential Voltage Probes
DP150/DP200pro
The DP differential isolation probes are an important accessory for any laboratory involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, whilst the oscilloscope can remain grounded. Using a DP150 or DP200pro probe, differential and floating measurements can be made on a variety of ac power systems like 230V/110V ac input power supplies, chopped and switching power supplies, thyristor controllers, variable speed motor drives (PWM signals), motor inrush current and measurement across current shunts. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope. The DP probes can be powered from a 9V battery or external power supply.
