Trafag pressure switches are used when pressure has to be controlled or monitored via an electric on/off switching signal. These switches are available in various designs in respect of indication, switching capacity and approvals (CE, Ex, Shipbuilding, Railways) as well as the sensor system involved. In mechanical pressure switches, a pressure sensor actuates an electric micro switch. In electronic pressure switches, a pressure sensor signal controls relays or transistor outputs.

Pressure Switches
Better under pressure. For years, manufacturers and operators of heavy-duty equipment have trusted Honeywell pressure and vacuum switches. They're proven under pressure, in applications constantly under attack from chemical splashes, performance spikes and other harsh environments. These switches sense a change in the pressure or vacuum, opening or closing an electrical circuit when the designated point is reached.
Honeywell offers an impressive line:
-Compact size
-Durable construction
-Enhanced set point integrity
-Customisation and modifications available
|
|
|
Complete product range for all industrial applications. Mechanical and electronic versions include cast and cabled specifications, “Ex” approved, switches in compact designs up to 600 bar for hydraulic and pneumatic applications.
|
|
The switch is designed so to open a three-pole electric circuit when the pressure in the system rises and to close it when the pressure decreases.
- Designed for electric boilers of coffee machines as main application.
- UL approved (USA), SEV-ASE approved (Switzerland).

Pressure Switches
Baratron Gauge Pressure Switch
The MKS Types 41, 42, 51 and 52 Vacuum, Atmospheric and Pressure Switches offer accurate and reliable protection for vacuum equipment, atmospheric switching, and vacuum/pressure processes. Designed for applications where a DC signal output is not required, these switches provide relay outputs that are readily interfaced with alarms, valve actuators, computers, process controllers, load locks and other protection devices.
The Type 41/42 switches reference atmosphere while the Type 51/52 switches reference vacuum. The Type 41/42 switches are often used to ensure a loadlock pressure has equilibrated to local atmospheric pressure before opening the door. The trip point on MKS' atmospheric switches can be set to trip above, below (reverse calibration), or exactly at current atmospheric pressure. Applications for the 51/52 switches include soft pumping, gas box switching, and safety interlocks.

Differential pressure indicators (DPIs)
"On condition" maintenance is a feature of modern fluid power technology. Our DPIs provide a signal to show the extent of filter blockage thus reducing maintenance time and costs by eliminating unnecessary filter element change.
Our range includes differential pressure indicators, switches and electrical indicators.
Microfiltrex can provide DPIs with many special features :
* Visual and/or electrical indication
* Thermal lock
* Flow surge suppression
* Non-reset function

The measuring principle of the mechanical pressure switch is a spring loaded diaphragm respectively for higher pressure ranges a spring loaded piston. The high mechanical service life, high contact rating and the compact design characterize the tecsis differential pressure switch.High quality parts and a integrated micro switch obtain a outstanding reliability and accuracy. The switching reliability and long service life are guaranteed by either a silver plated or optional gold plated contact.
Mechanical differential pressure switches are suitable for all areas, where an electrical signal is related to a given differential pressure value. They are especially designed for applications of controlling and monitoring differential pressures of filters, level measurement and flow measurement or for universal usage in machine and plant constructions.
