The Signet 2250 Hydrostatic Level Signet Flow Sensors for level and depth control has a one-piece injection-molded PVDF body and ceramic diaphragm for superior compatibility in corrosive liquids. Utilizing hydrostatic pressure, the 2250 Level Signet Flow Sensors disregards false level signals from steam vapors, foam or any other debris on the liquid surface. Two pressure ranges allow for optimal resolution matched to your sensing needs. Solid state circuitry eliminates drift (no internal potentiometers).
The type 2270 is a rugged, high performance ultrasonic level measurement sensor, having transducer and processing electronics incorporated in one single housing. It provides all the sophisticated echo detection features of the well accepted 2260 Ultrasonic Level Transmitters.
For single and multiple tank applications 2-wire sensors are recommended using either HART protocol or 4 to 20 mA for the direct communication with a panel mount controller or a PLC. Related Searchs: Signet Flow Sensors
Type 2280 Tuning Forks are suitable for level detection of liquids or granular, powdered solids. Mounted on tanks filling / emptying can be controlled using these devices just as well they can generate fail-safe alarms providing overfill- or dry run protection.
The operation principle is based on the electronic circuit exciting the fork probe making it vibrate. As the medium reaches and covers the fork its vibration changes. The electronics senses the change of vibration and gives output signal after a selected delay. Related Searchs: Signet Flow Sensors
The Multipoint Switch is based on the conductivity principle and can be applied to liquids with conductivity higher than 10 μS/cm.
The probes have to be placed into the tank for level detection. The probe length should be in accordance with the level to be detected. Filling liquid in the tank will change the electrical conductivity between the reference probe and the outer probes. The established connection will be converted and activate a relay providing the output.
The Guided Float Switch is designed for economical control of liquids in tanks. The switch is remarkable for its maintenance-free compact design and reed contacts with high switch capacity. It can easily be installed in water applications as well as in chemical applications.
The encapsulated reed contact is operated by the magnet. The switching function (N/O contact/N/C contact) is determined by the installation position. The switching function is reserved by simply rotating the switch through 180°. Related Searchs: Signet Flow Sensors
The Ultrasonic Gap Switch consists of Polyphenylene Sulphide (PPS) and is high corrosion resistant in most liquids. The gap switch is designed for high or low level alarm in different tank applications as well as pump control. However, if there is a liquid present, the signal will be transmitted across the gap and the integral electronics will switch the output circuitry to signal the presence of a liquid.
It can be mounted in any position in a tank using a 3/4" or 1" thread available in BSP and NPT thread forms.
The 2285 Level Float Switch is suitable for level switching of various liquids, sewage in shafts, tanks, basins or cisterns. The double-chambered float is made of injection molded tough polypropylene that ensures good waterproof protection.
The contacting microswitch is incorporated in the float. The cable of the level switch is absolutely waterproof and PVC insulated. Different control tasks such as liquid level monitoring and pump control can be realized. It is mercury-free contact and suitable for level switching of drinking water, raw water or polluted liquids with low solid content. Related Searchs: Signet Flow Sensors
