BETA switches. high quality safety applications.
BETA pressure & temperature switches are where excellence meets precision. At the heart of each switch is a high-quality, self-aligning spring-loaded piston sensor, meticulously designed for optimal performance in any application.
Our innovative design ensures maximum accuracy and reliability. By using a limited piston travel, pressure is transmitted directly from the process diaphragm to the microswitch, eliminating the need for complex linkages or mechanisms. This not only enhances precision but also provides complete protection against high overrange pressure, safeguarding your operations.
The piston sensor is ingeniously isolated from the process fluid by a diaphragm and static O-ring seal, further enhancing durability. With only three process wetted parts—the diaphragm, static O-ring seal, and process connection port—our switches combine simplicity with maximum flexibility, as these parts are available in an extensive range of materials.
BETA stands for a superior, high-quality solutions for your critical applications. Experience the difference that quality craftsmanship and innovative engineering can make.

switches. reliability independent of electronic control systems.
Switches are integral part of machines and devices, every installation has switches, they are crucial for process control, alarm, emergency shutdown (security), hence they fulfill most important tasks, applications are very diverse and types of switches hence numerous.
BETA has a range of pressure and temperature switches that are available in more than 10 million versions. Please talk to us, make your choice, BETA has the experts.
pressure switches. P. D. V.
Pressure switches detect a specific pressure threshold in a system, like a pump or compressor, and trigger an action when that pressure is reached.
- BETA supplies high quality pressure switch with various approvals and certificates.
- BETA switches can be supplied as pressure switch (P.), differential pressure (D.) switch or vacuum switch (V.).
- BETA switches can be used also as a hydraulic switch.
- BETA pressure switches can be supplied with ATEX-certificate. Ex-switch as an option.
- for different operation ranges (2-15 mbar / 12-1,250 mbar/ 0.3 -70 bar standard / 80-3,450 mbar). many more ranges are available.
- in clean lubricating and liquid fluids, they can be used as a hydraulic switch.
- the terminal block (a standard always available) realizes a secure and stable connection.
- reliability to the extrem.
temperature switches. T.
Temperature switches react to changes in temperature, activating devices like fans or heaters to maintain a desired temperature range, or shut down the process of an entire machine.
BETA temperature switches are based on the approved BETA pressure switch with an integrated 2-phase – (gas/liquid) temperature sensor. If process temperature increases, also the vapor pressure of the liquid increases. If pressure exceeds the defined response pressure value then the micro switch is activated.
- High quality temperature switches with various approvals and certificates.
- With an integrated 2-phase-temperature sensor.
- Independent from ambient temperature.
- Weather-proof and ATEX-instruments available.
- Very high repeatability and low hysteresis.
poles and throws.
Poles indicate the number of circuits a single switch controls. Throws indicate how many contacts the switch can choose between.
- an SPST (single pole – single throw) switch a single pole and a single throw, the circuit is open (off) or on (closed).
- an SPDT (single pole – double throw) switch has one pole but the switch can change between two different contacts, which switches the circuit.
- a single DPDT (double pole – double throw) switch controls two separate circuits with a single, synchronized action.
SIL 3 applicable.
The International Electrotechnical Commission’s (IEC) standard IEC 61508 defines Safety Integrity Level (SIL) using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements for both categories to achieve a given SIL.
- SIL is based on probabilistic analysis of the device.
