These miniature self-contained and powerful Retroreflective, Proximity (Diffuse) and Opposed Beam Pair Red Lion Photo-electric Sensors provide application flexibility in counting, positioning and object detection. All Red Lion sensor units are interchangeable with conventional 12 mm threaded barrel-type photo-electrics and inductive proximity sensors. Their small size, in addition to various mounting options, greatly increases alignment ease and application possibilities. All Red Lion Controls sensor units can be powered by supplies ranging from +10 to +30 VDC and are reverse polarity protected. The complementary NPN open collector (Current Sinking) outputs are protected from continuous overload and inductive load transients and are rated to 150 mA, with low saturation voltage and less than 10 µA offstate leakage current. In addition, no false outputs are generated at power-up.

Two versions of the Red Lion Photoelectric sensors are available, a 6 foot (1.83 M) long 4 conductor PVC jacketed cable or 6 inch long quick disconnect Pico-style connector provides supply input and transistor output. These miniature Red Lion Controls sensors offer a digital gain adjustment that uses a single sealed push button to streamline installation and setup.

Red Lion Controls Inductive Proximity Sensors detect the presence of metal objects that come within range of their oscillating field and provide target detection to "zero speed". Internally, an oscillator creates a high frequency electromagnetic field (RF) that is radiated from the coil and out from the sensor face. When a metal object enters this field, eddy currents are induced into the object. As the metal moves closer to the Red Lion proximity sensor, these eddy currents increase and result in an absorption of energy from the coil that dampens the oscillator amplitude until it finally stops. These Red Lion Controls Inductive Proximity Switches have a maximum sensing distance of 0.078" (2 mm) and 0.393" (10 mm) respectively, and operate over a wide power supply range.

The Red Lion proximity sensors are each housed in plastic with a top active face. The NPN transistor outputs are true open collector and are compatible with most Red Lion counter and rate meter input circuits. Maximum sensing frequencies are 2 KHz and 500 Hz respectively. In addition, the outputs are overload and short circuit protected. These sensors are shielded for flush mounting in metal applications.

The 2-wire Red Lion Proximity Sensor Models PSA-1B and 2B contain only the coil and oscillator circuit. With no metal object being sensed, the circuit oscillates and draws greater than 2.2 mA of supply current. As a metal object of sufficient size is brought into the sensing field, the oscillator amplitude dampens and finally stops, resulting in less than 1 mA of circuit current being drawn. This greater than 2.2 mA to less than 1 mA change in circuit current between oscillating and non-oscillating conditions is converted into a usable voltage signal (VS) by placing a resistor (RS) in series with the Red Lion sensor leads. Model TMP Thermocouple and RTD Red Lion Temperature Probes are field cuttable to the desired length. The Red Lion Controls temperature probes can be trimmed to within 3.5" (88.9 mm) of the probe tip allowing for greater application flexibility.

Accessory hardware is available to wire and mount the temperature sensor in the user's existing thermowell. Optional spring loaded fittings (sold separately) slide along the probe sheath to proper immersion depth as determined by the user. These fittings allow for strong contact between the Red Lion temperature probe and the thermowell to improve response. The spring loaded fittings are adjustable and reusable.

The Red Lion Controls PT Series Pressure Transmitters are designed to provide accurate and dependable pressure measurement, even in the most demanding applications. The reliability of solid-state design and the durability of the stainless steel case are the cornerstone of their design. Proven ceramic component technology allows long-term stability and high tolerance to overpressure conditions. The 4 to 20 mA output can easily be connect to any Red Lion process meter for monitoring and/or control.

Short circuit and reverse polarity protection are built-in to the circuitry, further enhancing this Red Lion pressure transmitters. The transmitter housing is constructed of stainless steel and provides an IP 67 level of protection. The fluid connection is a standard G 1/4 thread, while the electrical connection is a M12 connector. Additional pressure ranges and accessories are available on special request, contact the factory for more details.

In Red Lion Controls Retro-reflective Sensing, the scanner directs its light beam at a reflector and detects the returning reflected light. Objects being sensed break the light beam. Retro-reflective scanning is useful for detecting large opaque objects with surfaces having low reflectance. Distance between reflector and scanner can vary from 1' to 10' using a 1 1/2" Dia. prismatic reflector and up to 25' with a 3" Dia. reflector. Maximum distances should be reduced in areas where dirt and dust can settle on optic surfaces. Small objects can be sensed by reducing the reflector distance and masking the reflector. The sensitivity is adjusted to fall between the light level "seen" coming back from the reflector, and the residual reflected light "seen" when the object being sensed is in view. Retro-reflective scanning should not be used with glass, metal foil, or other objects having a high degree of surface reflectance. The output transistor turns ON when the scanner "sees" reflected light and turns OFF when beam breaks.
