ACC793 High Performance, Top Mount Accelerometers

Supported Applications

The Omega ACC793 series consists of high-performance, top-mount accelerometers designed for industrial vibration measurements. These sensors feature a hermetically sealed case suitable for harsh environments. The series includes models with intrinsic safety approvals available as options.

Operating Conditions & Performance

The ACC793 series operates within an ambient and process temperature range of -50 to 120°C (-58 to 248°F). A maximum current of 6 mA is recommended for operating temperatures above 100°C (212°F). The sensors provide a measurement range of 80 g peak with an output signal of 100 mV/g. Accuracy is specified as ±5% at 25°C (77°F).

Constructed from 316L SS, the housing maintains hermetic sealing to 10⁻⁸ cc/s and withstands a vibration rating of 500 g peak.

Configuration Options

The series supports multiple configurations through model suffixes and accessory options. The standard electrical connection utilizes a 2-pin, MIL-C-5015 style connector with an Amphenol 97-3106A-10SL-4S type mating connector.

Model Variants

• ACC793: Premium accelerometer with top exit connector.
• ACC793-FM: FM-certified intrinsically safe premium accelerometer with top exit cable. Approval covers Class I, II, III, Division I, Groups A, B, C, D, E, F, G; and Division II, Groups A, B, C, D, F, G.
• ACC793-CSA: CSA-certified intrinsically safe premium accelerometer with top exit cable. Approval covers Class I, Division I, Groups A, B, C, D.

Cables and Mounting Accessories

• ACC-CB7-10: 3.05 m (10') MIL/BNC twisted-pair shielded cable.
• ACC-CB7-10WP: 3.05 m (10') waterproof twisted-pair shielded cable.
• ACC-B3: Magnetic mounting base for flat surfaces, rated at 30 lbf.
• ACC-B5: Magnetic mounting base for curved surfaces, rated at 30 lbf.

Power Supply Options

• ACC-PS2: Rechargeable power supply with built-in amplifier (operates on 18 to 30 Vdc).
• ACC-PS3*: 115 Vac power supply.

The series includes a mounting stud and calibration data. Cables must be specified separately. A suffix of "-230" is available for the ACC-PS3 to support 230 Vac operation at no extra charge.

Key Product Differences

Differences within the series are defined by intrinsic safety certifications and accessory selection. The base model (ACC793) provides standard performance, while the -FM and -CSA variants add specific hazardous location approvals without altering the core measurement technology or housing dimensions.

Physical dimensions for all models in this series remain consistent: 61.47 mm (2.42 in) overall length with a diameter of 25.4 mm (1.0 in). The process connection is provided via a 1/4-28 tapped hole, and the unit weighs 112 g (3.9 oz).
