WARRANTY

Measurement Specialties, Inc. accelerometers are warranted during a period of one year from date of shipment to original purchaser to be free

from defects in material and workmanship. The liability of Seller under this warranty is limited to replacing or repairing any instrument or

component thereof which is returned by Buyer, at his expense, during such period and which has not been subjected to misuse, neglect,

improper installation, repair, alteration, or accident. Seller shall have the right to final determination as to the existence and cause of a defect.

In no event shall Seller be liable for collateral or consequential damages. This warrant is in lieu of any other warranty, expressed, implied, or

statutory; and no agreement extending or modifying it will be binding upon Seller unless in writing and signed by a duly authorized officer.

RECEIVING INSPECTION

Every Measurement Specialties, Inc. accelerometer is carefully inspected and is in perfect working condition at the time of shipment. Each

accelerometer should be checked as soon as it is received. If the unit is damaged in any way, or fails to operate, a claim should immediately

be filed with the transportation company.

SERVICE CONCERNS

If a Measurement Specialties, Inc. instrument requires service, first contact the nearest Measurement Specialties, Inc. representative. They

may be able to solve the problem without returning the unit to the factory. If it is determined that factory service is required, call Customer

Service at the regional headquarters for an RMA number before return.

RETURNS

All units being returned to the factory require an RMA (Return Material Authorization) number before they will be accepted. This number may

be obtained by calling Customer Service at the regional headquarters with the following information; model number(s), quantity, serial

number(s), and symptoms of the problem, if being returned for service. You must include the original purchase order number if under

warranty.

RECALIBRATION SERVICES

The Vibration Sensors Design Center and its two manufacturing facilities in China and France offer factory re-calibration services for

Piezoresistive, Piezoelectric and Integrated Electronics Piezoelectric (IEPE, ISOTRON, ICP, etc.) accelerometers. NIST (US), DKD

(Germany), COFRAC (France) traceable calibration services on sensitivity at 100 Hz (102 or 120 Hz in Europe) and full frequency sweeps are

offered. Contact the regional headquarters for pricing information.

DESCRIPTION

The Model 4020 & 4030 are low noise, signal conditioned DC accelerometers packaged in a durable molded housing with an integral cable

assembly. The accelerometers are offered in ±2g & ±6g ranges with a nominal 0-200Hz bandwidth and an operating temperature range of -

40°C to +85°C. The model 4020 is a dual axis configuration while model 4030 is a triaxial configuration.

INSTALLATION

The model 4020 & 4030 accelerometers are designed to be screw mounted. The following guidelines should be followed when screw

mounting these accelerometers.

The mounting surface should be clean and free of any residue or foreign material.

The mounting surface should be smooth and flat.

Torque screws to recommended limits using steel washers under the heads of the mounting screws. Use manual torque wrench (do not

use electric tools).

WIRING

The accelerometers are designed to be operated from 5-30Vdc excitation and provide a 0.5 to 4.5V full scale output. The output is DC-coupled

and should be used in single-ended mode. The sensor and electronics are fully contained in an internal Faraday cage which is connected to

the cable shield (floating with respect to circuit ground) for RFI protection.

A 2.5Vdc bias will be present on the output leads and the output of the accelerometer will be 0.5-4.5V full scale. The accelerometer should be

connected to the interface circuitry as detailed below.

CABLE ROUTING

The model 4020 & 4030 accelerometers incorporate a PVC jacketed cable with an integral shield. The cable assembly should be properly

secured at regular intervals during testing. It is recommended to use clamps, wax, or tape to secure the cable to minimize cable motion that

can add noise to the output signal. The initial attachment should be within two to three inches of the accelerometer.

Avoid routing cables near high-voltage wires and also ground the shield at the signal conditioner to minimize ground loops.

SELF-TEST OPERATION

The model 4020 & 4030 accelerometers incorporate a self-test feature. This feature is activated by grounding the self-test lead (gray). The

corresponding shift in bias output is shown in table below.

X = +210 ±90

X = +70 ±30

Y = -210 ±90

Z = -340 ±190

Z = -110 ±65

The self-test bias shift takes place no matter the orientation of the accelerometer. Sensitivity is unaffected. For normal operation the gray lead

floats and is not connected.

NOISE FLOOR SPECIFICATIONS

The model 4020 & 4030 accelerometers incorporate a LP filtered output for a high output signal. The noise specifications for this
