Product Details

Product Name:4-20mA integrated temperature transmitter

Manufacturer: Jiangsu Runyi Instrument Co., Ltd

Product brand: Runyi

Product Overview:

4-20mA integrated 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. It is an updated product for temperature measurement and control in modern industrial sites and research institutes, and is the * product of distributed systems and digital bus systems.

Product Features:

Ultra small (module diameter 44 × 18) integrated, with strong versatility.

Two line system with 4-20mA DC output and HART. 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.

◆ Adopting thermocouple temperature change can eliminate the need for compensating wires and reduce costs.

Various indication functions such as LCD, digital tube, 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).

Explosion proof rating: dIIBT4, dIIBT5.

◆ Protection level: IP54
