Seismic Signal Conditioning

The transmitter integrates the piezoelectric signal to velocity, filters to 10 Hz to 1 kHz, and scales 50.8 mm/s to 20 mA. Two-wire loop power is supplied by the receiving device. The measurement axis is perpendicular to the mounting surface. Output routes to Bently Nevada 3500 monitors, PLC analog cards, or DCS input modules.

Frequently Asked Questions

Q: What is the minimum loop supply voltage?
A: Dependent on total loop resistance and receiving device input impedance. Verify compliance voltage before wiring.

Q: Can the 177230 be mounted in any orientation?
A: The sensing axis is perpendicular to the mounting surface. Align this axis with the measurement direction. Mounting surface flatness affects high-frequency response.

Q: Is the 177230 compatible with 3500 monitoring systems?
A: Yes, with an I/O card configured for 4-20 mA input. Verify the 3-pin MIL-C-5015 pinout against the receiving cable.

Field Installation Guidelines

Mount on a clean, flat, machined surface. Remove paint, rust, or burrs. Torque the mounting stud to machine specification; do not over-torque. Route cable away from VFD output cables and high-voltage conductors. Maintain 300 mm (12 in) separation where practical. For runs over 30 m (100 ft), use shielded twisted-pair cable and ground the shield at the receiving device only. Fully engage and tighten the MIL-C-5015 coupling ring. Verify loop current with a milliamp meter before commissioning; expect approximately 4 mA at zero vibration. Confirm the approval code on the nameplate matches the hazardous area classification before installation in classified areas.
