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 UL, 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.

  • The ProtEX-MAX PD8-6300 offers all the functionality of the ProVu PD6300 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 a pulse output (NPN, PNP, TTL, switch contact, sine wave, etc.) flowmeter. It displays that signal on a dual-line, 6-digit Sunbright sunlight readable display. Flow rate is typically displayed on the upper line and the cumulative total is displayed on the lower line. The total overflow feature allows up to a 9-digit total and grand total to be displayed. The PD8-6300 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. It can be programmed and operated without opening the housing by using the built-in CapTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.

  • The ProtEX-MAX PD8-6001 explosion-proof level indicator offers all the functionality of the ProVu PD6001 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 level in feet & inches, instead of the usual decimal format. The meter accepts a process current (4-20 mA) or process voltage (0-5V, 1-5V, etc.) signal and displays that signal on a dual-line display with convenient feet and inches designations on the upper line. The upper display can even read fractions of an inch in 8ths or 16ths. The lower line can be used to indicate a tag or to display the input in another scale, such as volume in gallons or liters. The PD8-6001 includes a 24 VDC power supply to drive the transmitter and can be equipped with four internal relays and a 4-20 mA output. It can be programmed and operated without opening the housing by using the built-in CapTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.

  • The ProtEX-MAX PD8-7000 offers all the functionality of the ProVu PD7000 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 accepts a direct temperature input from a wide range of temperature measurement devices (type J, K, T, E, R, S, B, N, and C thermocouples and 100 or 1000 Ω platinum, 10 Ω copper, 120 Ω nickel RTDs). It displays the measured temperature in either degrees Fahrenheit or degrees Celsius on a dual-line, 6-digit Sunbright sunlight readable display. The meter includes automatic cold junction compensation for thermocouples and the ability to average up to ten (10) RTD sensors. The PD8-7000 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 CapTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.

  • The ProtEX-MAX PD8-6100 offers all the functionality of the ProVu PD6100 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 accepts strain gauge & load cell inputs and mV signals up to 300 mV (unipolar) and ± 250 mV (bipolar) for weight and force measurement applications. With a max output current of 350 mA at 10 V, it can support up to twelve (12) 350 Ω load cells (minimum load resistance of 28 Ω), making them ideal for multipoint weight measurement applications. The PD8-6100 strain gauge meter’s dual-line display and powerful dual-scale capability allows the measurement to be displayed in two different units of measure. Another use for the PD6100’s dual-lines is to simply display the units of measure on the bottom line. CapTouch through-glass buttons allow for access to zero, tare, and other functions without the need to remove the enclosure cover. The PD8-6100 includes a 24 VDC power supply to drive the sensors and can be equipped with four internal relays and two 4-20 mA outputs.

  • The Loop Leader PD6620 is an ATEX and IECEx approved, UL listed, intrinsically safe and nonincendive, loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, loop-powered backlight with a unique red backlight option for alarm conditions, and optional bargraph display (PD6628) provide a clear and attractive presentation of the process. All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The Loop Leader loop-powered rate/totalizer is built in a shallow-depth case with a IP65 front and features loop-powered backlighting and a wide -40 to 158°F (-40 to 70°C) operating temperature range. It doesn't matter if it's in hazardous areas, indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
