PLNX Multi-Channel Portable Load Indicator

The Model PLNX line of load indicators are 2 and 4 channel versions with the same basic circuitry and performance features as the Model PLN-D2. Additional features include different instrument cases, and switching provisions for two to four channels which accommodate up to four transducers. Indication is direct. Resolution is from 1 pound to 1000 pounds depending on full scale transducer capacity. Alternate display units are available. Operation is extremely simple. For normal use only three controls are involved. Turn on the power switch, set the channel, set no load balance or tare reading to zero, and begin reading applied loads.


A calibration check function is included to provide a quick test of the transducer and instrument integrity.

The readout system is fully contained in an aluminum alloy case that is both rugged and durable.

Power is provided by a set of rechargable batteries. Batteries and a recharger with retractable 110 or 220 Vac power cord, as specified, are included within the housing. In multi-channel units, excitation voltage is maintained on all transducers independent of channel switching.

Battery power allows complete freedom of use and provides 5-10 hours of continous usage depending on transducer resistance. A ratiometric measuring technique prevents battery decay from degrading system accuracy.

When battery voltage has decreased below a functional level, a visual display (flashing “:”) signals that recharging is needed.

Recharging is done by withdrawing the line cord from its sealed compartment and plugging into a standard 110 or 220 Vac, 60 or 50 Hz wall receptacle. Batteries are completely recharged overnight and can be left “on charge” indefinitely. The instrument is effectively usable on either battery or line power.


These portable battery powered load indicators can also be combined with other Strainsert components into a fully comprehensive force measurement system.
