Performance Under Extreme Pressure

For heavy washdown environments and HACCP requirements, choose Rice Lake's CW-90X checkweigher. The CW-90X features the toughest keypad available. This rigid piezo device is made to withstand sharp knife-point contacts, and is resistant to most contaminants and liquids.

The configuration menu of the CW-90X is accessible through the front keypad, eliminating the need to open the back of the indicator and expose the unit to moisture or contaminants. Access to these keypad controls can be limited to meet the operator's needs. 

The CW-90X will store detailed information for up to 50 separate IDs (expandable with WeighVault), allowing for easy recall of previously saved information. An adjustable contrast display is visible in any environment. 

Doran Scales



2200CW SS Checkweigher

2200CW Series Checkweigher Bench Scale

The 2200CW Series Bench Scale is an advanced high-performance checkweigher that combines a 2200CW advanced weighing indicator with a rugged Doran scale base and shown with optional column. The system features stainless steel construction and washdown protection — with components that are Built in the USA.

A large selection of base sizes and capacities, battery power option, scanners, and communications and networking equipment, and other accessories make this versatile indicator a smart choice for a range of weighing applications. 

Three and five band checkweighing guides the operator to accurately hit product targets quickly. Manufacturers can realize ingredient savings, improve quality control, achieve greater accountability, and support traceability goals

Key performance features include:

800 Product Memory: Quickly recall products from the scale database.  Product memory includes checkweigh limits, unit of measure, accumulator and counter values, tare, two data fields, checkweigh operation, and output configuration.

Doran QC Weigh software available: Configure the 2200CW to follow QC processes, collect data and provide reporting on product weights and accuracy. Record unique operator IDs, scheduled sample intervals with alarms, and data collection to confirm quality control tasks.

Doran Production Sentry software available: Control groups of scales to set the product to be checkweighed, collect data and provide reporting on product weights and accuracy, record operators and determine efficiency by line and operator.

Scale Bases: 304 stainless steel construction with a Quad-Spring shock-absorbing base design that provides 1000% overload protection in scale bases from 8" x 8" to 15" x 15", and provides 300% overload protection in bases 18" x 18" and larger.  Doran meets the demand for precision measurements of 0.1 g to multiple load cell applications up to 100,000 lb.

Multiple power options: 100-240 AC, 50/60Hz line power standard for permanent installation, a high-performance internal rechargeable battery option or 6-12 VDC input. 

Advanced Communications and Control

Connect, control, and communicate to any device or computer with the two standard RS-232 ports, eight standard outputs, two standard inputs, or a wide range of communication options. Connect with our wired Ethernet, Wireless Ethernet, Bluetooth, USB, 4-20mA. 

Control your process with our optional relays that can be mounted inside the enclosure to provide a turnkey solution.  Signaling includes audible alarms and light towers.

Communicate with the flexible and user-definable data strings to include tare, product ID, and time and date. 

Washdown protection. From the heavy gauge stainless steel to the innovative gasket design, the meets the IP69K classification for washdown protection.

Rugged design: All components of this system act as a defense against the damaging effects of shock, water, abuse, and other environmental factors that can cause costly repairs and production downtime.
