This high-precision and robust level sensor is designed to provide continuous gauging of liquid media levels in tanks. The measuring principle used by the sensor exploits the physical effect of magnetostriction and is largely unaffected by temperature. Magnetostriction is particularly ideal where...

The safe alternative to cloudy, breakable sight glasses. High Visibility - Brilliantly colored flags are easy to read, even at great distances. The indicator is isolated from the measure media; therefore, Suresites can be used where sight glasses are not even a consideration. Durability -...

Intrinsically safe controls have SPST isolated contacts and are FM Approved for use in Class I or II and Groups A through G hazardous locations. Sensitivity is field-selectable through the use of external resistors supplied with the control.

Zener Barriers: These passive, energy-limiting devices, provide intrinsically safe DC outputs for a variety of sensors such as level and flow switches...level indication transducers and transmitters...and many others. The maximum energy possible at the switch terminals of the SAFE-PAK® and Zener...

The A Series solenoid valve gives you a highly adaptable design for practically all applications requiring flow between CV 0.019 and 0.300. This robust 2- or 3-way miniature solenoid utilizes a stainless steel body to resist corrosion for most acids, alkaline solutions, and harsh environments....

These units solve the problem of point level sensing in tanks with inaccessible tops or bottoms, or at intermediate locations in larger tanks. Operation is positive and dependable. The float pivots with changing liquid level, displacing a shuttle which magnetically actuates a hermetically sealed...
