SL17 Submersible Pressure Transmitter
APPLICATIONS
Because of its small 17mm diameter
and rugged 316L SS construction, the
Ashcroft SL17 submersible pressure
transmitter is ideal for level applications, particularly in situations where
size or chemical compatibilities are an
issue. The SL17 utilizes piezo-resistive
technology (PRT) that is known for its
proven reliability and stability. Notably,
these transmitters can offer all ranges
equivalent from 1.5 psig through 300
psig while all units of measure and
cable lengths are customer-defined for
individualized specifications.
FEATURES
• Complete 316L SS Construction
• IP68 / NEMA 6P Housing
• Excellent Long-Term Stability
• 4-20 mA Output (2-wire)
• Unit of Measure Selection (Psig, Feet
or Meters of H20)
• Optional NIST Traceable Calibration
Chart (9-point)
TYPICAL APPLICATIONS
• Level (Groundwater / Bore)
• Wastewater
• Tank Level Measurement
