This device integrates a piezoelectric accelerometer, signal processing electronics, and a 4-20 mA linear proportional output into a single, robust housing. Engineered for reliability in extreme industrial environments, the 177230 seismic transmitter monitors overall vibration levels on casings or bearing housings, facilitating early detection of mechanical faults. By providing continuous data directly to a PLC, DCS, or SCADA system, it eliminates the need for a separate monitor rack, effectively reducing system complexity and operational downtime. Its multiple hazardous area approvals ensure it meets international safety standards for deployment in volatile oil, gas, and power generation applications.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown\u003c\/h3\u003e\n\u003cp\u003eThe 177230-01-02-05 model uses a specific alphanumeric configuration to define its operational parameters and safety ratings:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e01 (Measurement Range):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eConfigured for a velocity range of 0 to 25.4 mm\/s (0 to 1.0 in\/s) peak.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e02 (Frequency Response):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCalibrated for a frequency range of 3 Hz to 1 kHz (180 to 60,000 cpm).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e05 (Approvals):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCertified for Multiple Approvals including CSA\/NRTL\/C and ATEX\/IECEx for use in hazardous locations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e177230-01-02-05\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBrand\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBently Nevada\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOrigin\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eUSA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e131 g (Device), 1.5 kg (Shipping)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOutput Signal\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e4-20 mA DC proportional to vibration\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperating Temp\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-40 to +85 deg C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePower Consumption\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e12 to 30 VDC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCase Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e316L Stainless Steel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eTechnical FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the transmitter grounded to prevent signal noise?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 177230 transmitter circuit is internally isolated from the case.
