Sensor specifications

L-Strain vessel sensor

Measurement type: Wheatstone bridge, same as most load cells, 350 ohm.
Output sensitivity: 0.5 mV/V with applied load of 500 microstrain in steel structure.  Safe overload 400%.
Excitation voltage: 5 to 15 volts
Sensor material: Alloy steel, nickel plated.
Environmental: NEMA-4, IP 66 weatherproof.  Temperature range -30 to +80C.
Cable: 6 ft (2 m) 26 AWG 4-conductor shielded.
Wire colors: + excitation Red, - excitation Black, + signal Green, - signal White, shield Yellow.
Mounting: Three parallel mounting pads for use on flat surface.  Can be mounted on curved or uneven surface by use of spherical washers.
Limits on vessel capacity: No limit since structure is normally designed to support the vessel, which usually gives sufficient stress.  Practical limitations are with small vessels where structure is overdesigned and stress is too low for good accuracy.  Use Stress Calculator (below) on all applications to be sure of successful results.
