Technical Specifications

Sensitivity and Frequency Range

The sensitivity is 100 mV/g ±20% (10.2 mV/m/s² ±20%) . For frequency response, the range extends from 30 to 600,000 cpm (0.5 to 10,000 Hz) at ±3 dB. The measurement range reaches ±50g, accommodating a wide variety of vibration levels. As a result, this accelerometer captures both low-frequency machinery events and high-frequency bearing faults effectively.

Physical Dimensions and Weight

The hex size measures 11/16 inch (1.8 cm) for easy installation with standard tools. The height is 1.65 inches (4.24 cm) , making this sensor compact for tight spaces. The total weight is only 0.051 kg, minimizing mass loading on the measurement surface. Thus, the 200355-01-00-00 installs easily without affecting machine dynamics.

Housing and Sealing

The housing material is stainless steel , providing excellent corrosion resistance for industrial environments. The sealing method is welded hermetic , creating a completely sealed interior. The enclosure rating is IP68 , allowing continuous immersion in water. Additionally, relative humidity tolerance reaches 100% relative, condensing, non-submerged. Therefore, this sensor performs reliably in harsh, wet conditions.

Included Mounting Stud

The mounting stud option 01 provides a ¼-28 to M6 x 1.00 BeCu (beryllium copper) stud. This stud converts the sensor's ¼-28 female thread to M6 x 1.00 male thread. Beryllium copper offers excellent corrosion resistance and non-sparking properties. Consequently, this stud suits applications where spark prevention is critical.

Electrical Specifications

The electrical connector is a 2-Pin Mil-C-5015 type, positioned on the top of the housing. Output bias voltage ranges from 8 to 12 VDC. Excitation voltage requires 18 to 28 VDC with constant current excitation of 2 to 20 mA. Settling time reaches within 1% of bias in just 2.0 seconds. Output impedance is less than 150 ohms, and the discharge time constant is ≥0.3 sec. Furthermore, electrical isolation from the case exceeds 108 ohms.

Temperature Range and Shock Survivability

The operating temperature range spans -65°F to +250°F (-54°C to +121°C) . This wide range suits extreme industrial environments from freezing outdoor installations to hot turbine compartments. Shock survivability reaches 5,000 g peak , protecting the sensor during sudden impacts or installation accidents.

Performance Characteristics

Transverse sensitivity is ≤7% , minimizing measurement error from cross-axis vibration. Amplitude linearity is ±1% , ensuring accurate readings across the full measurement range. The mounted resonant frequency is 1500 kcpm (25 kHz) , well above the measurement bandwidth. Broadband electrical noise (1-10 kHz) is 350 μg (3,434 μm/s²) , providing clean signals for reliable analysis.

Mounting Specifications

The mounting thread on the sensor base is 1/4-28 Female . Maximum mounting torque ranges from 2 to 5 ft-lb (2.7 to 6.8 N-m) . Using the included BeCu stud, you can mount directly to M6 threaded holes on your machinery.

Sensing Element and Geometry

The sensing element material is ceramic , offering excellent stability and long-term durability. The sensing geometry is shear mode , which provides superior rejection of base bending and thermal transients. Consequently, this design delivers more accurate measurements in challenging mounting conditions.

Installation Guide

Follow these steps to install your 200355-01-00-00 correctly.

1. Prepare the Mounting Surface: Clean the machine surface thoroughly. Ensure the mounting area is flat and free of paint or debris.

2. Install the BeCu Stud: Thread the included ¼-28 to M6 x 1.00 BeCu stud into the M6 machine hole. Tighten to 2 to 5 ft-lb (2.7 to 6.8 N-m) torque.

3. Mount the Accelerometer: Thread the 200355-01-00-00 onto the installed stud. Hand-tighten firmly using the 11/16 inch hex.

4. Connect the Cable: Attach a mating 2-pin Mil-C-5015 connector to the sensor top. Ensure the connection is secure and properly sealed.

5. Apply Excitation: Provide 18 to 28 VDC constant current excitation at 2 to 20 mA . Verify the bias voltage falls between 8 and 12 VDC .

6. Verify Operation: Allow 2.0 seconds settling time. Then, check the output signal for proper response to machine vibration.

Frequently Asked Questions (FAQ)

1. What is the advantage of the beryllium copper mounting stud?
Beryllium copper (BeCu) offers excellent corrosion resistance and non-sparking properties. Therefore, the included stud suits applications where spark prevention is critical, such as in hazardous or explosive environments.

2. How does this accelerometer differ from the 200350-09-00-CN?
The 200355-01-00-00 includes a BeCu mounting stud (option 01) and has no agency approvals (option 00). In contrast, the 200350-09-00-CN has no stud but includes Country Specific approvals. Both share the same 100 mV/g sensitivity and IP68 rating.

3. Why does the shear mode geometry provide better measurements?
Shear mode design rejects base bending and thermal transients more effectively than compression mode sensors. Consequently, the 200355-01-00-00 delivers more accurate readings on thin-walled structures or surfaces with temperature variations.

4. Can this sensor operate in condensing humidity environments?
Yes, the IP68 enclosure rating and welded hermetic sealing allow operation in 100% relative, condensing humidity. However, the sensor is not rated for continuous submersion despite the IP68 rating.

5. What cable connector does this accelerometer require?
The 200355-01-00-00 uses a 2-Pin Mil-C-5015 top-entry connector. A mating connector is not included in the package. Order the appropriate cable assembly separately for connection to your monitoring system.
