Jewell Instruments introduces the model SMI-L 4-20mA Force Balanced Inclinometer. This powerful single-axis tilt sensor offers the same high performance and low cost as our standard Emerald Series, but with a convenient 4-20mA output. Units operate as a 3-wire current loop (Power, Return, Signal) for use with any 4-20mA PLC or data logger. Standard ranges are ±3° to ±90° deg. (0 deg. = 12mA). Utilizing a 2-pole Butterworth filter, the SMI-L also delivers exceptional noise rejection in a low cost inclinometer package. Custom ranges and filter passbands are also available on request. 4-20mA output makes the SMI-L ideal for geotechnical applications where long cable runs are required since there is no signal loss due to cable resistance.
The SMI-L is useful for geotechnical applications, industrial measurement and control, robotics, specialized research instruments or wherever 4-20mA output is required.
