For nearly a century, Rieker® Inc - a leading manufacturer of accurate, rugged inclinometers, tilt sensors, and accelerometers - has provided angle and slope measuring solutions for Aerospace/Defense, Aviation, Construction, Marine and Transportation industries.

Rieker's electronic units - including accelerometers, inclinometers, tilt switches, and angle indicators - are available with digital displays, customizable trip angles, RS232 output, and both audible and visual alerts. They are designed to notify, warn, control, or display information when needed based on a specific application. These electronic units continue Rieker's tradition of excellence for meeting the increasing need for advanced vehicle and equipment tilt monitoring and controlling. This unique long-term expertise in designing and manufacturing inclinometers, allows unprecedented control and measuring solutions for their customers.

Rieker offers a full line of inclinometer sensors and accelerometers for measuring the tilt angle of any object with respect to gravity. Input ranges from ±10° through ±80° with analog or digital pulse width modulated output available. The temperature compensated, signal conditioned inclinometers offer variable range settings with both 0 to 5VDC and 4 to 20mA outputs in single and dual axis packages (switch outputs and relays optional). The internal sensor construction of these units is fully encapsulated - providing ideal weatherproofing and durability. Rieker's low-cost static and dynamic accelerometers are very small, accurate, and shock resistant to 10,000g with ranges from ±3g to ±100g.

Rieker's SlopeAlert™ Tilt Warning System is a reliable, low cost solution for determining in-range and out of range tilt conditions. Connected to a lamp, horn, or solenoid relay, this compact single or dual axis unit can indicate both safe and unsafe conditions for as well as provide a control signal to shut down equipment. The rugged, weatherproof sealed construction stands up against harsh environments and severe vibration commonly found at off-road construction or industrial sites. Multiple trip settings are factory calibrated and can be arranged in a single axis to indicate caution before final alarm.

Rieker's manual or 'ball-in-glass-tube' style inclinometers provide instant and accurate tilt indication, will not rust or freeze up, and come in multiple degree settings with custom color zones.
