JUMO CANtrans p Ceramic Pressure Transmitter with CANopen Output, Type 402055

Name: JUMO CANtrans p Ceramic Pressure Transmitter
Brand: JUMO
SKU: CANtrans p Ceramic

Description

A ceramic pressure transmitter that talks CANopen directly

The JUMO CANtrans p Ceramic (type 402055) measures relative pressure in liquids and gases with a thick-film strain gauge on an alumina ceramic (Al2O3) sensing element and makes the digitised value available on a CANopen bus as a CAN slave. The DS 404 device profile for measuring devices and closed-loop controllers adds useful functions, and every setting can be made with standard CANopen software tools through the object directory (EDS). It is intended for machines and vehicles that already use a CAN network, where an analog 4 to 20 mA signal would otherwise need an extra interface. Ranges run from 0 to 1.6 bar up to 0 to 60 bar, plus vacuum-containing ranges down to -1 bar.

Useful functions built into the CANopen firmware

The block diagram lists the functions that distinguish the device from a simple converter. The ceramic signal is digitised at 12 bits and calibrated digitally at the factory. Sensor monitoring sends high-priority emergency telegrams on probe break or short circuit. The reading can be scaled to any engineering unit or to percent of range, an adjustable filter suppresses signal fluctuation, and the decimal place is freely selectable. Fine calibration offers an auto-zero function and an adjustable shift of the characteristic, range monitoring with freely chosen upper and lower limits reports results in a status byte, and a drag pointer stores the minimum and maximum pressure.

The date and name of the last service can be stored inside the transmitter. Measured values can be sent on different trigger conditions or only on a SYNC command, and heartbeat or node guarding supervise the device itself. NMT telegrams control its operating state. Further CANopen transmitters from JUMO are referenced as data sheets 402056 (pressure) and 902910 (temperature).

Wiring, accessories and enquiry details

Mechanical choices are limited by design. The wetted parts are stainless steel 1.4305 with the ceramic cell, and the process connection is chosen from four threads, G 1/4 and G 1/2 to DIN 3852-11 or G 1/4 to DIN EN 837 and 1/4-18 NPT. Profile seal rings are shown for the G 1/4 and G 1/2 DIN 3852 versions, and other connections are available on request. The nominal mounting position is unrestricted. The datasheet limits the medium temperature to -20 to +85 degC, so check the process against that limit.

The M12 plug has five pins: shield on 1, V plus on 2, V minus on 3, CAN_H on 4 and CAN_L on 5, and the datasheet recommends a screened 5-wire cable. Accessories include M12 line sockets (00337625, 00375164, 00419130 and 00419133), a tee-piece (00419129), a 2 m extension cable (00461589), a bus termination resistor (00461591) and a PC CAN interface with configuration software for USB (00449941).

For an analog alternative in a similar size see the published dTRANS p30 and the pressure instrumentation category. When you enquire, state the pressure range, process connection, seal material (FPM or FFPM, which has PTFE-like properties), CAN baud rate and node ID needs, and whether a customer-specific configuration is required.

About brand

JUMO is the German maker of temperature sensors, process controllers, pressure transmitters and liquid analysis instruments. Moritz Kurt Juchheim founded it in Fulda in 1948 as M. K. Juchheim KG, making glass thermometers with six employees. The name JUMO comes from the founder's name. It is still a family company headquartered in Fulda, and the parent company has been called JUMO GmbH & Co. KG since 2003.

Choosing a temperature sensor starts with the range and accuracy. A Pt100 RTD is accurate and stable from about -200 to 600 °C and is the usual choice in process plants. A thermocouple (type K or J, for example) covers much higher temperatures and responds faster but is less accurate. The wiring also matters: a 3-wire or 4-wire Pt100 connection cancels the resistance of the cable, while a 2-wire connection adds an error that grows with cable length. That is why a head-mounted transmitter is often fitted close to the sensor.

Where JUMO products are used

In Oman and the GCC, JUMO sensors and controllers are used in oil and gas and chemical plants, food and beverage production, plastics and metal heat treatment, HVAC and district cooling, water and wastewater treatment, swimming pools and marine applications.

Ordering JUMO products: what we need

Send the JUMO type number and the full order code from the label (for example 902020/10-...). For probes, add the sensor type (Pt100, Pt1000, type K or J), the number of wires, the insertion length and diameter, and the process connection. For controllers, add the input, outputs and supply voltage.
