Explanation:
Specially developed for such devices and machines which control limit values via weight measurements, Esit SMART-P is a small and simple weighing indicator with a rugged and durable housing. It is a reliable and cost-effective solution in electronic detection of and protection against overloads upon cranes and elevators.
Properties:
- Impact-resistant plastic housing
- 4-digit red LED weight display
- Dust and humidity-proof membrane keyboard with tact keys
- Taring, zeroing, function and adjustment keys
- Zeroing within the entire measurement range
- Gain adjustment for load cell output
- RS232/RS485 serial output
- Internal relay output
- Analog output (4-20 mA)
- Analog output (0-5 V)
