Transverse response remains less than 5% of the axial sensitivity during normal operation.
Amplitude linearity is within ±2% up to 63.5 mm/s peak velocity measurement.
Mounted resonant frequency is at least 9 kHz when properly installed with a stud mount.
Output bias voltage is 10.1 Vdc ±1.0 Vdc between Pin A and Pin B of the connector.
Dynamic output impedance is less than 400 Ω for stable signal transmission.
Broadband noise level measures 0.229 mm/s peak under standard operating conditions.
Base strain sensitivity is rated at 0.43 mm/s per microstrain for minimal installation error.
Internal electronics are fully isolated from the transducer case to prevent interference.
Maximum supported cable length reaches 305 meters with no signal quality loss.
The unit includes a 32‑foot cable as part of its standard configuration.
Mounting uses a plate stud 3/8‑in 24 to M8x1 adapter for versatile equipment mounting.
Operating temperature range spans -40°C to +85°C for harsh industrial environments.
Storage temperature extends from -40°C to +100°C for safe transport and storage.
Shock survivability is rated up to 5000 g peak without permanent damage.
Humidity tolerance is 100% condensing, as the unit is sealed against moisture.
Magnetic field susceptibility is less than 0.0068 mm/s/gauss at 50 gauss and 50–60 Hz.
The 190501-12-99-02 has a typical weight of 297 grams for lightweight installation.
Mounting surface diameter is 33 mm, with a total height of 82 mm.
Case material is 316L stainless steel for corrosion resistance and durability.
It uses a 2‑pin 316L stainless steel MIL‑C‑5015 top connector.
Recommended mounting torque is 4.5 N·m ±0.6 N·m for secure installation.
Polarity is defined with Pin A positive when velocity moves from base to top.
The transducer supports mounting in any orientation for flexible equipment placement.
The 190501-12-99-02 carries CSA/NRTL/C certification for Class I, Division 1.
It also holds ATEX/IECEx/CSA approvals for Class I, Zone 0/1 hazardous areas.
