Model 900 Biaxial Clinometer
The dual-axis Model 900 is an inexpensive, gravity-referenced clinometer with analog voltage output and compact dimensions. Sold without a housing, its small size and performance make it an excellent choice for many OEM, test, and measurement applications. It is available in high-gain, standard, and wide-angle versions, each with a different angular range. Model 900 accepts a wide input voltage range and provides high-level single-ended outputs that are easily measured with any voltmeter or digital recording system. Viscous damping and temperature measurement are available as options.
Model MD908 ‘IRIS’ Tilt Switch
The IRIS Tilt Switch and Controller is a powerful tilt controller device that combines a digital, dual-axis clinometer and advanced firmware features in one compact unit. This remarkable instrument enables you to measure and respond to rotational movements in any direction concerning the unchanging gravity vector. Units ship standard with a 24-inch hook-up cable. IRIS is an ideal choice for OEM applications, where it can be used to maintain platform levelness, avoid tip-over conditions, prevent out-of-range movement, and perform other control functions.
Modutec MC1 Series – 250° High Torque Taut-Band Movements Meters
Modutec MC1 movements are technically advanced and offer outstanding features not found in other 250° movements. Their unusually small size and their refined taut-band suspension mean high performance in the area of accuracy, tracking, and repeatability. Their unique design includes shock limiters and vibration stops which combined with optional Fluidyne®
viscous damping gives them exceptional durability and stability in difficult environments.
Mounting is usually by means of three tapped brass standoffs which are swaged to either the front or the back of the movement, as ordered, permitting installation within its 1.25″ O.D.
Dials can be mounted to standoffs on the front of the movement; however, MC1 movements are usually ordered with a universal mounting plate (see drawing) installed. This not only serves as a dial mount but also coordinates with the mounting requirements of many domestic and imported movements. Note that front standoffs are not available when the universal mounting plate is installed.
Standard movements come without front and back dust caps. Either or both will be installed when specified on order.
