What is a Pressure Switch?
Pressure switches are signal elements, that can be used for measuring pressure in pressure lines for gases, vapours or liquids.
In general pressure switches have one or more fixed or adjustable switching contacts.
Each switching contact has a setpoint (● SP). This setpoint corresponds to a pressure value setted on the pressure switch.
When rising above or falling below this value the switching contact within the pressure switch is triggered.
Due to inaccuracy the re-set point (● BSP) does not exactly match the setpoint.
The difference between setpoint and re-setpoint is called hysteresis or switching differential (↕ SD)
Once the switching contact is triggered, setted pressure values are transformed into electrical or pneumatic signals which are necessary for the control and regulation of processes, e.g. safety and alarm devices.
What is a MANOCOMB Pressure Switch?
The MANOCOMB® pressure switch is a modular precision pressure instrument based on a force-balance measuring system, that actuates either one or two switching contacts.
These switching contacts can be comfortably adjusted on a calibrated set value input scale (class 1.0).
To protect adjusted setpoint from readjsuting, a sealable version is available.
Optionally the MANOCOMB® precision pressure switch can be equipped with an integrated pressure gauge (actual value indicator, class 1.0) and/or integrated pressure transducer (analogue signal 4 - 20 mA or 0 - 10 V, 0,5% FS) inside the same housing.
Based on the modular system an enourmous number of housing types, switching contact types, pressure, differential pressure and vacuum ranges, process connections and electrical / pneumatic connections is available.
This great variety qualifies the MANOCOMB® precision pressure switch for all measuring points and operating conditions.
The MANOCOMB® is also suitable for critical applications, e.g. as safety pressure limiter with internal interlock. Approvals cover SIL, VdTÜV leaflet 100, Pressure Equipment Directive, Gas Applicances Directive and/or ATEX.
Differences between MANOCOMB® precision pressure switches and conventional pressure switches
● high precision and extremely robust force-balance measuring system with bellows and calibrated spring. Without moving axes , turning motions, rotations, hinges or pistons the measuring systems works completely friction free!
● the measuring system is mounted free of tension or torsion in the housing!
● each switch contact has its own measurement system!
● very comfortable switching point adjustment with calibrated reference scale (class 1.0) without tools or reference instruments!
● large selection of switching contacts, for example micro switches, inductive contacts, air cutting contacts, pneumatic valves!
● optionally integrated pressure gauge (class 1.0)!
● optionally integrated pressure transmitter (analogue signal 4 - 20 mA or 0 - 10 V, 0.5% FS)!
Technical advantages
● The measuring system has no parts subject to wear and tear and is exceptionally precise:
hysteresis: depending on contact approx. 0,5 - 3,5%
repeatability: depending on contact approx. 0,03%
● virtually unlimited life span!
● insensitive to pressure surges, shock and vibration!
● the adjusted switching point is not affected by body tension!
● High accuracy. Each contact is adjustable independently over the entire measuring range (0 - 100%) and does not interfere with the other!
● For adjusting the switch point no reference instrument is needed. Settings can be comfortably made on-site without affecting safety. Adjusted values can be clearly read from the setpoint scale and compared to the actual pressure value!
● Large selection of switch contacts to optimize the control/switching performance, eg high switching capacity, intrinsically safe circuit, pneumatic output signal!
● Simplified installation arrangements by integrated instruments!
Economical advantages
● Lowest losses in uptime due to highly accurate set point adjustment!
● Compact design with small dimensions and simplified installation arrangements by integrating other instruments!
● Proven design without mechanical stress: you do not need any wear parts or spare parts!
● Exact reproducibility and long term stability, which saves you a lot of maintenance hours per year and corrections to the setting!
