Key to its high performance and low cost is Kavlico’s patented ceramic capacitive sensing element and integral hybrid circuit for reliable signal conditioning.

The sensor has a quick response time of .05 to 3 seconds, a broad operating temperature range of -30°C to +85°C, features a glass filled plastic molded housing, and is easily installed in hostile environments.

Operating from a 5 Vdc regulated power supply, the sensor provides a 0.5 through 4.5 Vdc output with 0° at 2.5 Vdc. Other features include EMI, RFI, and ESD protection, low power consumption, over-voltage and reverse polarity protection, and excellent long-term stability, repeatability, and hysteresis.

In addition to the Tilt sensor, Kavlico designs and manufactures custom sensors for a wide variety of OEM, application specific requirements utilizing our ceramic capacitive, silicon micro-machined integrated capacitance and piezoresistive technologies.

Combined Pressure & Temperature Sensors

For OEM"s requiring measurements in demanding environments, Kavlico"s combined pressure and temperature sensor is the answer. This 4-wire device operates on a 5 volt regulated power supply and provides a 0.5 to 4.5 Vdc linear signal proportional to pressure while temperature output is resistive (thermistor).

This combination sensor is available in standard pressure ranges of 0-15 to 0-250 psia/psig whith higher, custom range pressure ranges available for high volume OEM"s. Packaged in a rugged, cost-effective brass housing with a variety of electrical connectors (DIN, Packard, flying leads), these sensors offer EMI protection, overpressure protection up to 5x rated pressure and an industry leading wide operating pressure span of -40 degrees C to +125 degrees C (please use degree sign).

Kavlico sensors offer superior long-term stability and excellent hysteresis/repeatability characteristics. Minimum operating life span is 10 years.

 

Level Sensors

Kavlico"s fuel tank level sensor for OEM applications has been specifically designed for on & off-highway vehicles, replacing unreliable mechanical float mechanisms. The design has NO MOVING PARTS and is available in both top and bottom mounted versions and can be configured with application specific insertion lengths.

The sensor operated on a low 5 Vdc power input and provides a .5 to 4.5 Vdc output proportional to level. It features full-scale accuracy of ±5% that includes long term stability, repeatability, hysteresis, interchangeability and temperature. Kavlico"s variable capacitive sensing element and integral ASIC with hybrid circuit for reliable signal conditioning are key to its high performance.

The unit has an operating temperature of -40°C through +80°C, built-in reverse polarity and over-voltage protection. The 1/2-14 NPT or M22-2.5 fittings allow for easy installation.

Available in brass or stainless steel configurations, the sensor is supplied with a built-in 3-pin electrical connector that mates to a Packard Metri-Pack Series 150 sealed connector. Additional fittings and connectors can be incorporated to meet custom OEM specifications for drop-in replacement.

The sensor"s excellent vibration resistance (10 G"s peak to peak sinusoidal) make this device the sensor of choice for fuel tank"s used in a wide variety of off-road, marine, industrial, military, and power generation applications, providing better accuracy and reliability than conventional level devices.

P6000

Kavlico"s compact (< 3 cm in length) P6000 provides a new, economical, and durable option for system designers seeking a highly accurate yet small footprint pressure sensor for dry media medical applications such as respirators, oxygen concentrators, and CPAP equipment. The sensors can also be utilized for dry or wet media applications in a variety of industrial applications as well where sensor size and mounting options are a concern. Additionally, Kavlico can custom design sensor packaging for those with unique configuration needs.

Providing a fully calibrated, temperature compensated 0.5V to 4.5V linear analog output proportional to pressure; the sensor provides increased flexibility when it comes to the pressure sensor’s physical location and mounting. The device is offered with (3) mounting configurations: Option 1: Flying leads allow it to be positioned remote from the PCB. Option 2: The sensor can be connected to the PCB through a miniature 4-pin connector. Option 3: With lead wires for through hole PCB mounting.

The P6000 is available in gage or absolute pressure ranges from 2.5 PSI to 100 PSI. Pricing is approximately $15 in volumes of 1000 units.

sCAP1

Kavlico’s barometric absolute pressure (BAP) sensor chip is an integrated Micro-Electo-mechanical System (MEMS) sensor that utilizes a signal conditioned variable capacitive silicon sensors technology that has years of field proven service. This low-cost pressure sensor chip is well suited for a variety medical and automotive applications due to its miniature size and high reliability.

The sensor die design can be easily configured into the required final package specifications as the die size is a mere 1.5 x 1.2mm.

The sensor is based upon the Silicon MEMS capacitor, as capacitance varies with external pressure applied upon it; the capacitance values are electronically converted into a high DC Voltage output gain of 150 to 200 millivolts by the on-chip signal conditioning circuit, so integration into the application is considerably simplified. As opposed to other techniques, the sCAP 1 has excellent stability, thereby providing extremely repeatable measurements.

The sensor chip itself features a 1.5 to 5.0 Vdc operating range. The highly reliable design is available in pressure ranges of 0 to 240 KPa (0 to 1800mm Hg) absolute. The device operates on a low power source, drawing much less than 1 mA at 1.5 Vdc.

The sensor can withstand an overpressure of 2X the range and has an operating temperature range of -20° to +40°C.
