Main specs / meaning:

• Type: Differential pressure transmitter
• Brand: Nagano Keiki
• Model: KL11
• Medium: Gas / air
• Sensor: Miniature silicone diaphragm
• Output: Analog signal, depending full model code
• Use: Measures small pressure difference between high side and low side
• Applications: Filter clogging, airflow, clean room pressure, duct pressure, gas pressure monitoring

• ype: Vibrating rod level switch
• Use: Minimum or maximum level detection in silos / tanks
• Material detected: Bulk solids, granules, powder, pellets, cement, plastic granules
