Ordering Information Breakdown

The model number 200150-23-05 contains specific configuration details. The base model 200150 represents the general purpose accelerometer family. The “-23” mounting stud option specifies a 3/8-24 to M16x2.0 adapter. This option includes a 1-3/8 inch hex plate stud for secure mounting. The “-05” approvals option indicates multiple certifications. Specifically, this unit holds CSA, ATEX, and IECEx approvals for hazardous areas. Therefore, the 200150-23-05 suits international installation requirements.

Electrical Specifications

All electrical specifications are measured at +25°C (+77°F). Sensitivity at 80 Hz reaches 10.2 mV/(m/s²) or 100 mV/g with ±12% tolerance. Measurement range spans ±245 m/s² which equals ±25 g. Frequency range referenced to 80 Hz falls between 10 and 1000 Hz. In cpm units, this range equals 600 to 60,000 cpm. Mounted resonant frequency exceeds 20 kHz or 1200 kcpm. Amplitude linearity stays within ±2% from 1 to 10 g peak. Transverse sensitivity measures ≤7% for accurate single-axis measurement.

Settling Time and Excitation

Settling time for the 200150-23-05 reaches ≤300 milliseconds. This settling occurs within 5% of the bias voltage. Excitation voltage required is 4.7 to 5.5 Vdc. Polarity is defined as SIG+ positive with respect to SIG-. Quiescent current consumption stays below 800 µA. Output bias voltage measures +2.5 ± 0.23 Vdc. These electrical characteristics ensure compatibility with Trendmaster systems.

Mounting Adapter Details

The 200150-23-05 features a unique mounting adapter configuration. The accelerometer itself has a 3/8-24 female thread. The adapter converts this thread to M16x2.0 male thread. A 1-3/8 inch hex plate stud provides easy wrench access. This design allows installation on metric machine mounting pads. Consequently, the 200150-23-05 fits European and Asian equipment standards.

Environmental Specifications

Axial shock limit reaches 49,050 m/s² peak or 5,000 g peak. Operating temperature range spans -40°C to +105°C (-40°F to +221°F). Hermetic sealing meets 5×10⁻⁸ atm•cc/s maximum leakage rate. Relative humidity tolerance reaches 100% condensing conditions. However, do not submerge the 200150-23-05 in liquid. The sealed construction protects against moisture and contamination.

Physical Dimensions and Materials

Size measures 17.5 mm across hex flats by 45.7 mm in height. In imperial units, this equals 11/16 inch by 1.8 inches. Weight is 58 grams or 2.0 ounces typical. The base accelerometer mounting thread remains 3/8-24 female. Recommended mounting torque ranges from 2.7 to 6.8 N•m (2 to 5 ft•lbf). The sensing element uses durable ceramic material. Sensing geometry follows shear design for reduced base strain sensitivity. Housing and connector material is 316L stainless steel. This material provides excellent corrosion resistance for the 200150-23-05.

Extended Temperature Capability

The accelerometer assembly withstands -55°C to +121°C (-67°F to +250°F). This wider range applies to the sensor and connector materials. However, electrical specifications only apply within -40°C to +105°C. Any DC4 compound used with mating cables requires 24 hours cure time. After curing, the assembly provides its best moisture protection.

System Compatibility

The 200150-23-05 works with ProTIM option standard acceleration-to-velocity channel type (-01). This combination suits general application monitoring needs. The accelerometer connects to Trendmaster 2000 and Trendmaster Pro systems. Users should verify compatibility before ordering.

Installation Guidelines

Follow these steps to install the 200150-23-05 correctly.

1. Prepare Mounting Surface: Clean the machine mounting pad thoroughly. Ensure the M16x2.0 threaded hole is free of debris.

2. Attach Adapter Plate: Screw the 1-3/8 inch hex plate stud into the machine. Tighten to appropriate torque for your equipment.

3. Install Accelerometer: Screw the 200150-23-05 into the adapter plate by hand. Then tighten to 2.7 to 6.8 N•m torque.

4. Connect Cable: Attach a compatible Bently Nevada cable to the accelerometer connector. Hand-tighten the coupling nut only.

5. Connect to Monitor: Route the cable to your Trendmaster system. Connect to the acceleration-to-velocity input channel.

6. Verify Operation: Apply excitation voltage of 4.7 to 5.5 Vdc. Then check the output bias voltage for +2.5 Vdc nominal reading.
