Integrated temperature transmitter

WZPBIntegrated temperature transmitterIt is a combination of temperature sensors and transmitters that converts temperature signals within the range of -200~+1600 ℃ into a two-wire 4-20mA DC electrical signal in a very simple way, which is transmitted to displays, regulators, recorders, DCS, etc., to achieve accurate measurement and control of temperature.Integrated temperature transmitterIt is an updated product for temperature measurement and control in modern industrial sites and research institutes, and a product of distributed systems and digital bus systems.

Two line system with 4-20mA DC output. Long transmission distance and strong anti-interference ability.

Cold end, temperature drift, non-linear automatic compensation.

High measurement accuracy and good long-term stability.

The temperature module adopts epoxy resin casting technology internally, which is suitable for use in various harsh and dangerous places.

Integrated design, simple and reasonable structure, can directly replace ordinary assembled thermocouples and thermistors.

Mechanical protection IP65.

Using thermocouple temperature change can eliminate the need for compensating wires and reduce costs

Various indication functions such as LCD, digital display, pointer, etc. facilitate timely monitoring on site.

When the on-site ambient temperature is above 70 ℃, the transmitter and on-site display instrument can be installed separately (isolated). If conditions do not permit, the method of extending the length of the protective tube can be used to achieve the purpose of protecting the temperature transmitter.

Explosion proof rating: dIIBT4, dIIBT5. CT4.CT6

Protection level: IP54, IP65

It can form an integrated on-site installation structure with thermocouples and thermistors, and can also be installed as a functional module in detection equipment and instrument panels for use.
