Explosion-Proof Thermocouple

Explosion-Proof
Precision Digital manufactures a wide variety of explosion-proof indicators and controllers which can be powered via either loop or line power and carry all the major approvals, such as FM, CSA, ATEX and IECEx. These instruments will accept a wide range of inputs, such as 4-20 mA, strain gauge, pulse, thermocouple, RTD and Modbus and can be equipped with relays, 4-20 mA outputs and serial re-transmission. They all feature displays that can be easily read in various lighting conditions, from wide angles, and from considerable distances.

Explosion-Proof Thermocouple

  • The ProtEX-MAX PD8-765 explosion-proof, large-display, process and temperature meter offers all the functionality of the Trident X2 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. PD8-765's huge 1.2" (30.5 mm) sunlight readable display that is visible from over 30 feet away. This explosion-proof indicator can be field programmed to accept process voltage (0-5 V, 1-5 V, etc.) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples. The intensity of the display can be adjusted to compensate for various lighting conditions, including direct sunlight. The meter can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons or the RS485 serial communication port with free Modbus® protocol. Options for the PD8-765 process and temperature indicator include 2 relays, a 4-20 mA output, and a 24 V transmitter power supply.

  • The ProtEX-MAX PD8-7000 offers all the functionality of the ProVu PD7000 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. 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 up to 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 RS485 serial communication port with free Modbus® protocol.
