Preamplifier PAM2

Product catalog summary

Product Description: The PAM2 is a preamplifier designed to enhance strain gauge signals by 100 times, making it suitable for applications where the distance between the force sensor and control cabinet exceeds permissible cable lengths. It is compatible with AME, DCM, DCX, and DMA systems.

Special Features: The PAM2 can be combined with various systems and significantly reduces noise susceptibility due to its low output impedance.

Scope of Supply: The package includes a preamplifier housed in an aluminum enclosure.

Versions: The PAM2 is available in three options: Option 1 with 1 channel, Option 2 with 2 channels, and Option J with a strain gauge supply voltage of 5 V.

Technical Specifications: The preamplifier operates with a supply voltage of 24 V DC ±10% and has a current consumption of approximately 50 mA. It provides a strain gauge excitation supply voltage of 10 V DC (or 5 V DC for Option J) with a maximum current of 160 mA. The nominal input voltage is ±20 mV, with a maximum of ±40 mV, and the amplification factor is 100. The device is protected to IP65 standards and operates within a temperature range of 0 to 60°C (32 to 140°F).

Construction: The PAM2 is constructed with an aluminum enclosure measuring 140 x 140 x 90 mm and is fixed using four M6 screws.

Terminal Assignments: The terminal assignments for DCM and DCX include connections for power supply, ground, and amplified signal outputs for one or two sensors, depending on the version. The wiring diagrams for AME, DCM, DCX, and DMA amplifiers are provided for proper sensor connection.

Ordering Example: An example of ordering the PAM2 is provided, indicating the type and options available.

Catalog excerpts

Product Description Preamplifier PAM2 Special Features □ Combinable with AME, DCM, DCX and DMA □ 100-fold increase of strain gauge signal Scope of Supply - Preamplifier in aluminum enclosure Version - Option 1: 1 channel - Option 2: 2 channel - Option J: Strain gauge supply voltage 5 V Construction: Aluminium enclosure 140 x 140 x 90 mm (L x B x H) Fixing: 4 screws M6 In production plants the distance between force sensor and control cabinet is often higher than the permissible length of cable. For these applications is the preamplifier PAM is especially suitable. The low level of the strain gauge sensor signals will be raised to a 100-fold value and with its low output impedance the noise susceptibility is significantly reduced. The settings for the zero point are made on the downstream amplifier.
