Features

Level Switch

The Model 1100 in-line flow level switch from Thomas Products, Southington, CT, monitors insufficient or excessive liquid flow rates. It is factory preset for flow rates of 0.4 to 100 gpm. Other models are available with a vane to adjust the set point in the field. Standard process connections range from ¾ to 3in. NPT. Standard materials include brass, bronze, type 316 stainless steel, and Monel. The switch withstands pressures of up to 1,200 psi at 100°F and is qualified to MIL-S-16032.

Rotary Position Sensor

The RS 1500-200 rotary position sensor from Macro Sensors, Pennsauken, NJ, measures the angular displacement of rotating elements such as quarter-turn ball and butterfly valves, air flow dampers, and diverter gates used in packaging and postal sorting machine. It is available with a 24Vdc input and 0 to 10Vdc output (RSE 1500-120), or with a two-wire, 4 to 20mA loop-powered transmitter I/0 (RSI 1500-120).

Air Bearing Actuator

The Airpel-AB air bearing actuator from Airpot, Norwalk, CT, has a specially shaped stainless steel piston that is precisely fitted to a borosilicate glass cylinder. Introducing pressurized air into the air bearing’s cylinder produces a true bearing airflow effect around the piston. The air cushion prevents the piston from contacting the outside wall. The resultant cylinder delivers long piston life and requires no lubrication.

Linear Motor Stages

The ANT95-XY and ANT95-XY-H dual-axis linear motor stages from Aerotech, Pittsburgh, PA, allow travel in X and Y dimensions. They allow critical elements such as orthogonality, straightness, and flatness to be optimized. The technology has no hysteresis or backlash, enabling 5nm resolution, 50nm repeatability, and 250m accuracy in both X and Y dimensions. Both the 25 × 25mm or 50 × 50mm travel options come with a 60mm profile height.

Cylinder Position Sensor

A magnetically actuated linear displacement sensor from Turck, Minneapolis, MN, the Q25L, detects piston position on pneumatic cylinders. Suited for applications requiring precise signal transmission over long measuring distances, it is available with measuring ranges of 100, 125, 160, and 200mm. By utilizing an external magnet as a position indicator, the sensor can be used in additional applications such as moving platforms, point line measurement, or other specially designed equipment where a cylinder is not present.
