Hazardous Area
Precision Digital manufactures a wide range of rugged meters and controllers designed for quick and easy display of a variety of process signals in harsh or hazardous areas. These signals include 4-20 mA, 0-10 V, strain gauge, pulse, thermocouple and RTD. Our hazardous-area instruments are approved by FM, CSA, ATEX, and IECEx as explosion-proof, intrinsically safe, and nonincendive. Many of our explosion-proof models feature SafeTouch® through-glass buttons which ensure safe operation without the need to remove the cover. Intrinsically safe, loop-powered instruments derive their operating power from the 4-20 mA current loop with a relatively low voltage drop, preventing the need to run additional, costly power lines into the hazardous area.

  • PD8-6310 ProtEX-MAX Explosion-Proof Pulse Input Batch Controller

    The ProtEX-MAX PD8-6310 offers all the functionality of the ProVu PD6310 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is a pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The PD8-6310 includes a 24 VDC power supply to drive the flowmeter and can be equipped with four internal relays and a 4-20 mA analog output.

  • PD8-6262 ProtEX-MAX Explosion-Proof Dual Analog Input Flow Rate/Totalizer

    The ProtEX-MAX PD8-6262 offers all the functionality of the ProVu PD6262 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is specifically designed to display flow rate and total from two (2) analog output (4-20 mA, 0-5 V, 1-5 V, etc.) flowmeters. It displays these signals on a dual-line, 6-digit Sunbright sunlight readable display. The two display lines can be used to show both flow rates simultaneously, to alternate between the two inputs showing both the flow rate and total of each, or to show the result of math functions performed on the flow rates and totals. The total overflow feature allows up to 9-digit totals and grand totals to be displayed. The PD8-6262 can be equipped with four internal relays and a 4-20 mA analog output. It can be programmed and operated without opening the housing by using the built-in SafeTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.

  • PD8-6310-WM ProtEX-MAX Explosion-Proof Weights & Measures Approved Batch Controller

    The ProtEX-MAX PD8-6310-WM offers all the functionality of the ProVu PD6310-WM as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is an NTEP certified, pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications which has been certified as a Weighing and Measuring device. These versatile NTEP certified batch controllers provide excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch through-glass buttons for simple operation and menu navigation without having to remove the cover. The Weights and Measures approved controller is equipped with a mechanically secured, tamper-proof, programming lockout feature. This consists of a cable with a compression seal that is used to prevent access to a programming lockout jumper. The PD8-6310 includes a 24 VDC power supply to drive the flowmeter and can be equipped with four internal relays and a 4-20 mA analog output.
