The Mercoid® SERIES 3200G Smart Pressure Transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART® Communication. The Series 3200G is capable of being configured with the zero and span buttons, a field calibrator is not required for configuration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores configuration settings and stores sensor correction coefficients in the event of shutdowns or power loss. The Series 3200G is FM approved for use in hazardous (Classified) locations. The 100:1 rangeability allows the smart transmitter to be configured to fit any application.

Features:

• Completely configurable using zero/span buttons (no calibrator required)
• Automatic ambient temperature compensation
• Fail-mode process function

Product Details:

SERIES DA/DS are the best pressure switches made. The Mercoid DA/DS Series is one of the world’s broadest lines of pressure switches. The DA/DS Series has extremely high sensitivity and great repeatability. The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point. Deadband, the difference between high and low setpoints, is adjustable over the full-scale. The DS Models are equipped with a single external adjustment for setting operating point only. For mercury-free switches, choose between the snap action switch or hermetically sealed snap action switch. Hermetically sealed mercury switch also available.

Features:

• Visible calibrated dial provides an easy and fast check without having to open device causing dangerous conditions to operators
• On/off indication (except hermetically sealed snap switch models) gives operator clear indication of state of switched equipment that could be located in another location
• Adjustable or fixed deadband supports control applications by reducing equipment wear-out by unnecessary recycling
• External switch setpoint adjustments reduces set-up time
• Pressure ranges of full vacuum to 8000 psig gives application designers the ability to specify standard equipment, simplifying install and training, and reducing servicing costs
• UL listed, CSA approved many models FM approved to support rigorous process applications and regulations
• General purpose, weatherproof or explosion-proof enclosures for a variety of indoor or outdoor environments meeting the needs of multiple applications and uses
