The electronic pressure switch DS 200P is the successful combination of — intelligent pressure Switch — digital Display and is suitable for the usage with viscous and pasty media. As standard the DS 200P offers a PNP contact and a rotatable display module with 4-digit LED display. Optional versions like e.g. an intrinsically safe version, max. 4 contacts and an analogue output complete the profile. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 40 bar — accuracy: 0.25 % / 0.35 % / 0.5 % FSO — rotatable and configurable display module — indication of measured values on a 4-digit LED display — configurable contacts (switch on / switch off points, hysteresis / window mode, switch on / switch off delay) Optional Features: — analogue output — IS-Version Ex ia = intrinsically safe for gases — customer specific versions

Compressor pressure switch, rated at 150 PSI.

Schaffer Diaphragm gauges are designed for use on slurries, viscous or corrosive fluids that would normally attack or block standard bourdon tube gauges. 316 Stainless Steel full safety pattern case. Implementing specialist materials for both the connection and diaphragm enable the Shaffer Diaphragm gauge to be configured for use on any gaseous or liquid media including suspended solids or powders. The direct drive from the diaphragm to the movement ensures a more positive indication of pressure than other models of tube gauges. Offering a full range of screwed connection sizes and materials, Schaffer Diaphragm gauges can operate at pressure ranges as low as 30 mBar with the option to permit units to withstand a maximum pressure of 70 bar.

The function of a Pressure Switch is to provide a path for an electrical circuit that is triggered at a certain pressure. Example uses are: •Oil pressure warning light in an automobile •Pump controller (turn well pump on and off) •Air compressor control •Industrial process signaling A pressure switch must have a process connection (usually threaded for a pipe or tube) and an electrical contact that is connected to wires or terminals. They may sense rising or falling pressure and most are adjustable, so the contact will engage (or turn on the electrical circuit) at a desired pressure setting. They can be pneumatic (air and gases) or hydraulic (water, oil or fluids) or even strictly mechanical. The internals can be a diaphragm capsule, a small chamber backed by a spring or a bourdon tube. The contact is usually copper points but can also be a mercury (in glass) tip switch. Unlike Pressure Transducers which give an analog electrical signal proportional to the amount of pressure, these
