Description
The Bently Nevada 177230 is a loop-powered seismic transmitter that sends machine casing vibration (broadband velocity rms) to a PLC, DCS or SCADA system as a 4–20 mA signal, with full-scale ranges of 12.7, 25.4 or 50.8 mm/s and no field configuration needed. A second, unbuffered acceleration output (100 mV/g, 2.5 Hz to 10 kHz) is available for detailed analysis.
It has a ceramic shear sensing element in a 316L stainless steel case with a MIL-C-5015 connector, runs on 12–30 V DC and −40 to +85 °C, and is approved intrinsically safe (Ex ia IIC T4) and for Division 2.
Argonmark Ltd supplies Bently Nevada instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
